How Things Work in Thailand

Thailand has a strong tipping culture in tourist areas, driven largely by the fact that service wages are low and tips form a significant part of workers' income. At restaurants, leaving 20–100 THB (depending on the meal quality and total bill) is appreciated. Many upscale restaurants add a 10% service charge — check your bill. For massage therapists, 50–100 THB per hour is standard. Taxi drivers do not expect tips but rounding up the meter fare is polite. At hotels, 20–50 THB for housekeeping and bellboys is appropriate.

Bangkok has a good public transit system including the BTS Skytrain (elevated rail), MRT (underground subway), and river boats. The Rabbit Card works on BTS lines and can be bought at any BTS station. For MRT, buy tokens or a stored-value card at the station. Tuk-tuks are iconic but overpriced for tourists — they are primarily a tourist experience. Motorbike taxis (with orange vests) are fast for short distances but require negotiating a price first. Grab (the local Uber equivalent) is widely used, metered, and highly recommended over hailing taxis.

Thailand is actually a global medical tourism destination — private hospitals like Bumrungrad International, Bangkok Hospital, and Samitivej Hospital in Bangkok offer world-class care at a fraction of Western costs. English is widely spoken at private hospitals in major cities. Costs are significantly lower than in the US, UK, or Australia, but still expensive without insurance. In rural areas and islands, healthcare quality drops significantly. Pharmacies (marked with a green cross) are everywhere and pharmacists can advise on and dispense many medications without a prescription.

Thailand's lese-majeste law (Section 112 of the Criminal Code) makes it a serious criminal offense to defame, insult, or threaten the King, Queen, heir apparent, or regent. This applies to social media posts, verbal comments, and even liking a Facebook post deemed disrespectful. Penalties are 3–15 years per count. Drug laws are severe — possession of Category 1 drugs (heroin, meth) carries the death penalty; marijuana was legalized for medicinal use in 2022 but regulations are evolving. Disrespecting Buddhist temples or monks is a significant cultural offense.

Thailand has a dedicated Tourist Police division (1155) that operates 24 hours and has English-speaking officers — this is the best number for tourists. The regular police line (191) may have limited English. For ambulance, the national emergency medical line is 1669. Private ambulance services in cities are often faster. Narenthorn EMS Center coordinates emergency medical services. On popular islands, some resorts have their own emergency contacts — always ask your accommodation for local emergency numbers on arrival.

Thailand is relaxed about clothing in general tourist areas, beach resorts, and cities. However, temples (wats) and sacred sites have strict dress code requirements: shoulders and knees must be covered for both men and women. Many temples provide sarongs to borrow at the entrance. The Grand Palace in Bangkok enforces this particularly strictly and guards will turn you away. Beachwear is appropriate at beaches and resorts but should not be worn while visiting towns, markets, or any non-beach area. Thai people dress conservatively themselves in religious settings.

Thailand allows alcohol sales but with restrictions. The legal drinking age is 20. Sales are restricted to specific hours at most venues: 11am–2pm and 5pm–midnight. This creates the curious situation where you cannot legally buy alcohol at a 7-Eleven at 3pm. On election days (national, provincial, and local), alcohol sales are completely banned nationwide for 24 hours. During important Buddhist holidays (like Makha Bucha, Visakha Bucha, and Asalha Bucha), alcohol sales are also banned. Beach towns and tourist areas sometimes have extended licenses.

Thailand has an active bargaining culture at traditional markets, floating markets, street markets, and independent clothing or souvenir stalls. The key rule is to always bargain with a smile and good humor — Thai culture values keeping the interaction pleasant. A reasonable starting offer is 50–60% of the asking price. If the vendor accepts immediately, you have probably offered too much. In malls, department stores, and 7-Eleven-style shops, prices are completely fixed. Tuk-tuk and songthaew fares are always negotiated before the journey.

Thailand is generally very photography-friendly. Tourist sites, markets, temples, and landscapes can all be photographed. However, there are important exceptions. Inside temple buildings (ubosots), photography is sometimes banned — follow posted signs and staff direction. Photographing monks without asking is considered disrespectful; always request permission first. Photographing the military, police, government buildings, or the royal family in an unflattering way is illegal. As mentioned in local laws, anything that could be interpreted as disrespectful to the monarchy is a serious legal risk.

Thailand operates largely 7 days a week. 7-Eleven, FamilyMart, and other convenience stores are open 24/7 throughout the year. Shopping malls are typically open daily (10am–9pm or 10pm). Street markets are often busiest on weekends. Government offices are closed on weekends and public holidays. Banks are closed on weekends but ATMs operate 24/7. On major Buddhist holidays (there are around 5 per year), alcohol sales are banned and some businesses close out of respect. Songkran (Thai New Year, mid-April) effectively shuts down major cities for 3–5 days.

Grab operates across Thailand for both car and motorbike rides with upfront pricing, making it the safest and most transparent option for tourists. Metered taxis are plentiful in Bangkok but drivers sometimes refuse the meter for tourists — insist firmly or walk away and hail another. Tuk-tuks are fun for short tourist trips but are not practical or economical for regular transport. Motorbike taxis wearing orange vests are ideal for short hops through traffic. BOLT also operates in Bangkok as a Grab competitor. In Chiang Mai, songthaews (shared red pickup trucks) are the main local transport, with fixed routes and negotiated fares.

Tap water throughout Thailand is not potable for drinking and should be avoided even for brushing teeth in some areas. Bottled water is inexpensive at 7–15 baht per 500ml bottle and available at every convenience store and street stall. Ice served at established tourist restaurants is generally made from purified water and considered safe. Ice from unknown street food sources carries a slightly higher risk, particularly at small rural stalls. Refillable water stations are found throughout cities offering purified water at 1 baht per litre, making them a cost-effective and environmentally friendly alternative.

Almost all Thai ATMs charge a flat 220 baht foreign transaction fee regardless of the amount withdrawn, so it is best to withdraw larger amounts less frequently. Bangkok Bank, Kasikorn (KBank), and SCB ATMs are the most widely available and reliably accept international cards. Cash remains essential for street food stalls, markets, temples, and tuk-tuks that do not accept cards. Carrying 1,000–2,000 baht on you at all times is a sensible precaution. The Wise card significantly reduces conversion fees when used at ATMs. When prompted by the ATM, always decline dynamic currency conversion and choose to be charged in THB.

Thailand has three main mobile networks: AIS, DTAC (now merged into TrueMove H), and TrueMove. All three sell tourist SIM cards at Suvarnabhumi and Don Mueang airports upon arrival, and at convenience stores throughout the country. Tourist SIM packages typically cost 299–499 baht and include unlimited or high-speed data for 15–30 days. Coverage is excellent in Bangkok, Chiang Mai, Phuket, Koh Samui, and most resort areas. Signal can be patchy in jungle, mountain, and remote island areas. Airalo eSIM is a convenient option for those with compatible unlocked phones, allowing activation before departure.

Thailand runs on 220V/50Hz electricity. Thai sockets are unusually accommodating, accepting Type A (two flat pins), Type B (two flat pins plus a round earth), and Type C (two round pins) plugs, which covers the majority of international devices including US, European, and Australian plugs. Most modern electronics (laptops, phone chargers, cameras) are dual-voltage and work fine. A universal travel adapter is still useful as a backup but many travellers find they do not need one. Power supply is reliable in Bangkok and major cities. On smaller islands and in remote areas, brief power outages can occur, particularly during rainy season storms.

While haggling is a healthy and expected part of market shopping in Thailand, tourists are also targeted by organised scams. The tuk-tuk gem and tailor scam involves a driver offering cheap rides that conveniently stop at commission-paying shops. The jet ski damage scam in Phuket is particularly financially damaging — operators claim pre-existing scratches were caused by you and demand hundreds of dollars; always photograph the jet ski thoroughly before and after rental. Overpriced ping pong show tickets sold by touts promise a set price but add hidden charges inside. Fake tour operators sell excursions that do not match descriptions or do not run at all.

Thailand ranks as one of Southeast Asia's safer destinations for tourists. Petty theft — pickpocketing in crowded markets and on busy transport — is the primary concern. Motorbike bag snatching has been reported in parts of Pattaya and certain Bangkok neighbourhoods; wear bags across the body and away from the road. Drug-related scams involving planted substances and police demanding bribes are very rarely documented but do exist. Sex tourism areas in Pattaya, Patong, and Bangkok carry associated risks of theft and robbery. Political protests occasionally occur in Bangkok and can turn unpredictable — avoid large gatherings if tensions are visible.

The wai — pressing palms together at chest level and bowing slightly — is the traditional Thai greeting and shows respect; reciprocating when someone wais you is polite. The head is considered the most sacred part of the body in Thai culture and touching another person's head, even a child's, is deeply offensive. Feet are considered the lowest and least sacred part, so never point your feet at a person, a Buddha image, or a monk. Thai society places enormous value on avoiding public anger or confrontation — raising your voice or showing obvious frustration is considered losing face and reflects very badly. Women must never touch a Buddhist monk or hand anything directly to one.

Thai is a tonal language with five tones, making it genuinely difficult for English speakers to master quickly, but a handful of key phrases make a significant positive difference. In Bangkok, Phuket, Chiang Mai, and on major tourist islands, English is spoken at most hotels, restaurants, and shops. Outside tourist zones, English proficiency drops sharply and Google Translate (with camera mode for signs) becomes invaluable. Thai people respond warmly when tourists attempt even basic phrases. Key phrases to learn: 'sawadee krap' (male greeting) / 'sawadee ka' (female greeting), 'khob khun krap/ka' (thank you), and 'pet nit noi' (a little spicy).

Thailand's beaches — including Koh Samui, Phuket, Koh Phi Phi, and Koh Tao — are among the most beautiful in the world. However, real hazards exist. Box jellyfish are extremely dangerous, particularly along the Gulf coast from March to June, and can cause fatal stings. Regular jellyfish are more common, especially around Koh Samui from February to April. Rip currents are a serious risk on the Andaman coast (Phuket, Krabi) during monsoon season. Phuket uses a coloured flag system: green (safe), yellow (caution), red (do not swim) — the red flag rule is enforced by lifeguards and must be respected.

Thailand drives on the left side of the road, which catches out visitors from right-hand-drive countries. An International Driving Permit (IDP) is legally required to rent and drive any motorised vehicle, including scooters, though this is inconsistently enforced. Scooter rental is extremely common at beach destinations but Thailand has one of the highest road accident rates in the world, and tourists on scooters without experience account for a significant share of serious injuries. Police checkpoints targeting unlicensed foreign riders are common in tourist areas, with on-the-spot fines. Driving at night in rural areas is particularly hazardous due to unlit roads, stray animals, and other vehicles without lights.

Thai cuisine is one of the world's great food cultures and street food at busy, high-turnover stalls is generally very safe and excellent quality. Iconic dishes include pad thai, green curry, massaman curry, som tam (papaya salad), and mango sticky rice. Spice levels can be extreme — always say 'pet nit noi' (a little spicy) unless you are comfortable with high heat. Tipping around 10–15% is appreciated at sit-down tourist restaurants but is not expected at street food stalls. Vegetarian and vegan options are widely available — 'jay' means vegan in Thai. Seafood on islands is superb but always confirm prices before ordering, as lobster and large fish are charged by weight and bills can be surprisingly high.

Buddhist temples (wats) are the most common religious sites tourists visit in Thailand. Shoes and hats must be removed before entering, and both men and women must cover shoulders and knees — sarongs are often available to borrow at the entrance. Avoid turning your back to a Buddha image when leaving a room; back out or turn sideways respectfully. Buddhist monks must not be touched by women, and women must not hand objects directly to monks. In the Muslim-majority south (Phuket has mosques; the deep south near the Malaysian border is predominantly Muslim), modest dress for all visitors is required inside mosques, and non-Muslims should ask permission before entering.

Thailand has two distinct coastal regions with different weather patterns. The Gulf coast (Bangkok, Koh Samui, Hua Hin) and Andaman coast (Phuket, Krabi, Koh Phi Phi) are both best from November to April — dry, sunny, and with calm seas. The rainy season runs from May to October on most of the country, characterised by heavy afternoon showers rather than all-day rain. Koh Samui has its own distinct rainy season from October to December, making it a good choice when the Andaman coast is wet. Chiang Mai is cooler and drier than the coasts. Overall, November to February is the sweet spot — cool enough to be comfortable and dry across virtually all regions.

Street food dishes cost 40–80 baht (roughly $1–2) and are often better than restaurant equivalents. Songthaews — shared pickup truck taxis — cost a fraction of tuk-tuks for the same journey in cities like Chiang Mai. Local restaurants on side streets away from tourist zones charge 30–50% less than the same dishes on the main tourist drag. Temple entry is frequently free or just 20–50 baht, with notable exceptions like the Grand Palace. Chiang Mai is consistently cheaper than Bangkok for accommodation, food, and activities. The islands (Koh Samui, Phuket) are the most expensive areas. Guesthouses with kitchen access allow self-catering for even greater savings.
