How Things Work in Mexico

Tipping is a core part of service culture in Mexico and a significant part of workers' income. At sit-down restaurants, 10–15% is the norm; 15–20% for excellent service. Petrol station attendants who pump your gas and clean your windshield expect 5–10 pesos. Hotel porters and housekeeping staff appreciate 20–50 pesos per service. Tour guides typically receive 50–100 pesos per person for half-day tours.

Mexico City has an extensive and very affordable Metro system at approximately 5 pesos per ride, supplemented by Metrobús BRT lines and peseros (minibuses). Uber and InDriver operate widely in major cities and are strongly preferred over hailing street taxis due to documented safety risks. In smaller towns and rural areas, colectivos (shared minivans or taxis) are the standard affordable option and run fixed routes at fixed prices. Long-distance travel is well served by comfortable first-class ADO bus lines.

Mexico has a two-tier health system. Public hospitals (IMSS, ISSSTE) are for residents only and are often overcrowded; tourists should use private hospitals, which are modern and well-equipped in cities like Mexico City, Cancún, Los Cabos, and Guadalajara. Farmacias (pharmacies) are ubiquitous — chains like Farmacias del Ahorro and Farmacias Similares stock a wide range of medications without prescription at low cost. Travel insurance with medical evacuation cover is strongly recommended, especially in remote areas.

Mexico has partially decriminalized small amounts of certain drugs for personal use (cannabis up to 5g, cocaine up to 0.5g), meaning personal possession may not lead to arrest, but it remains a legal grey area and is still federally illegal. Bringing any firearm or ammunition into Mexico — even accidentally — is a serious federal crime with mandatory prison sentences. Archaeological artifacts cannot be removed from the country. State and municipal laws vary significantly; always check local rules.

Mexico unified its emergency number to 911 in 2016, covering police, ambulance, and fire services nationwide. The 078 line is a dedicated tourist assistance service offering help in English and Spanish for tourists in distress, lost documents, or other non-life-threatening situations. The US Embassy in Mexico City can be reached at +52 55 5080-2000. LOCATEL (5658-1111) assists with lost persons in Mexico City. Response times vary significantly between urban tourist zones and rural areas.

Mexico's dress culture is relaxed and informal in most settings. Beachwear is fine at coastal resorts but should not be worn away from the beach or pool. Catholic churches — including major sites like the Basilica de Guadalupe — require covered shoulders and knees; some lend wraps at the entrance. Indigenous communities, especially in Chiapas and Oaxaca, may have specific dress requirements for visitors and it is important to ask and comply respectfully. Upscale restaurants and nightclubs in Mexico City may have smart-casual dress requirements.

The legal drinking age across Mexico is 18 years, and ID checks are common at venues. During elections, the Ley Seca (dry law) bans all alcohol sales — sometimes for 24–48 hours — and this applies to hotels and restaurants as well as shops. Drinking in public spaces is illegal in Mexico City (CDMX) and several other municipalities, though enforcement varies. Beach destinations and tourist resort zones are generally permissive. Mezcal, tequila, and micheladas are the iconic local drinks.

Haggling is a normal and enjoyable part of shopping in Mexico's open-air markets (mercados), craft markets (artesanías), and with street vendors. It is culturally accepted and vendors often expect it. A common approach is to offer around 60–70% of the asking price and negotiate from there. However, in shopping malls, supermarkets, pharmacies, and restaurants, prices are fixed and haggling would be considered inappropriate and rude. At tourist markets, the first price given to foreigners is almost always inflated.

Mexico is generally welcoming of photography. Ruins, streets, markets, and most public sites can be photographed freely. However, the San Juan Chamula church in Chiapas has a strict absolute ban on all interior photography — cameras will be confiscated and visitors ejected. Other indigenous ceremonies and sacred sites across Oaxaca and Chiapas prohibit photography; always ask permission first. Photographing military checkpoints or personnel is illegal and can result in immediate detention and equipment confiscation.

Mexico's convenience store chains — OXXO, 7-Eleven, and Extra — operate 24 hours a day, 7 days a week, including all public holidays, making them reliable fallbacks for food, water, SIM cards, and cash. Supermarkets and most retail shops open on Sundays with regular or slightly reduced hours. Banks and government offices close on all public holidays (Mexico has around 7 mandatory and several optional public holidays). Museums often close on Mondays. Markets and street food stalls are frequently busiest on weekends.

Express kidnapping using street taxis (pirate taxis) is a well-documented and ongoing problem in Mexico City, Guadalajara, and other major urban areas. Victims are picked up, taken to ATMs to withdraw cash, and sometimes held overnight. App-based services like Uber and InDriver are far safer because trips are tracked, the driver is identified, and there is a digital record. At airports, always use the official pre-paid taxi booths (Sitio) inside the terminal rather than touts outside. In tourist resort areas like Cancún's Hotel Zone, authorized sitio taxis are generally safe.

Tap water throughout Mexico is not safe to drink for tourists, and even many locals use purified water for drinking. Large refillable garrafón jugs (20 litres) are found in hotels and rental apartments; confirm your accommodation provides drinking water. Bottled water is cheap and available everywhere, including OXXO stores. Ice in tourist restaurants is generally made from purified water, but it is worth asking. Brushing teeth with tap water is usually fine for most travellers, but sensitive stomachs should use bottled water.

ATM skimming and card cloning is widespread in Mexico, particularly at standalone machines in tourist areas, convenience stores, and shopping centres. The safest ATMs are those located inside a bank branch during opening hours (BBVA, Banorte, HSBC). Always inspect the card slot for tampering. When asked whether to pay in your home currency or pesos, always choose pesos — DCC (dynamic currency conversion) gives a very poor exchange rate. Wise or Revolut debit cards minimize foreign transaction fees significantly.

Telcel is Mexico's largest network and offers the widest coverage including rural and coastal areas. Prepaid SIM cards are sold at OXXO convenience stores nationwide without requiring ID in most cases, and data plans are affordable. AT&T Mexico is a good alternative with solid data speeds in cities. Airalo eSIM works well for travellers wanting to set up connectivity before landing. Hotel and café Wi-Fi is widely available but can be slow; a local SIM is strongly recommended for reliable maps, Uber, and translation.

Mexico's electrical system is essentially identical to that of the USA and Canada: Type A (two flat parallel pins) and Type B (two flat pins plus a round ground pin) sockets, running at 127 volts and 60 Hz. North Americans can plug in directly with no adapter. European and UK travellers will need a Type A/B plug adapter. Most modern laptop chargers, phone chargers, and cameras are dual-voltage (100–240V) and work fine with just an adapter. Power cuts are rare in tourist areas but can occur in rural regions.

Mexico has several well-known tourist scams. The timeshare scam lures tourists with promises of free gifts, discounted tours, or lottery wins, leading to high-pressure multi-hour sales presentations. Fake police or officials may approach tourists and demand to inspect wallets or bags for 'drug checks' — this is a theft operation. Short-changing is common at busy markets; always count your change. ATM skimming (card cloning devices fitted to machines) is a persistent and serious problem. Taxi overcharging is common when not using a rideshare app.

Mexico's safety situation is highly region-specific. Major tourist destinations including Mexico City's historic centre, Cancún, Los Cabos, Puerto Vallarta, Oaxaca City, and Mérida are well-travelled by millions of tourists annually and are broadly safe with normal precautions. However, several states have active cartel violence and US State Department Level 4 'Do Not Travel' advisories: Sinaloa, Zacatecas, Colima, and Tamaulipas. Petty theft, pickpocketing, and bag snatching are common in crowded markets and on public transport. Night travel between cities by road carries elevated risk.

Mexican culture places high value on personal warmth, family, and formal respect. Greetings are important — a handshake for initial meetings, a cheek kiss between acquaintances, and always greet everyone individually in a group. Professional titles such as Licenciado, Ingeniero, and Doctor are used widely and show respect. Refusing food or drink offered by a host is considered impolite. Social events rarely start on time — arriving 30 minutes late to a dinner is normal. Formal business settings require punctuality.

Spanish is the official and overwhelmingly dominant language throughout Mexico. In major tourist areas — Cancún hotel zone, Los Cabos resort strips, Mexico City's Polanco neighbourhood, and busy archaeological sites — basic to functional English is spoken by service staff. Outside these zones, English proficiency drops sharply. Google Translate's camera mode is excellent for menus, signs, and written text. Attempting even basic Spanish phrases (gracias, por favor, ¿cuánto cuesta?) is warmly received and usually improves service.

Mexico's beaches use a colour-coded flag system: green (calm, safe to swim), yellow (caution, moderate conditions), red (high risk, strong currents), and black (dangerous, no swimming). Rip currents on Pacific coast beaches at Puerto Escondido, Sayulita, and Zipolite cause tourist drownings every year. Caribbean coast beaches (Cancún, Tulum, Playa del Carmen) are generally calmer. Cenotes — freshwater sinkholes of the Yucatán — offer excellent swimming in calm, clear water and are a major attraction. Always swim near lifeguarded areas where possible.

Mexicans drive on the right, the same as the USA and Canada. Speed limits are posted in kilometres per hour. Topes (speed bumps) are found on nearly every road, including highways through villages, and are often poorly marked — hitting one at speed can cause serious vehicle damage or loss of control. Night driving between cities carries elevated risk due to poor road lighting, roaming livestock, and security concerns in certain regions. Toll roads (cuotas) are generally well-maintained, safer, and worth the cost for inter-city travel.

Mexico has one of the world's great cuisines, recognised by UNESCO as Intangible Cultural Heritage. Street food from busy, high-turnover stalls is generally safe and delicious — look for stalls with long queues of locals. The menú del día (set lunch menu) at local restaurants typically offers soup, a main course, and a drink for 80–120 pesos (roughly 4–6 USD), making it the best-value meal of the day. Tipping 10–15% at restaurants is standard. Spice levels are adjustable — ask for salsa on the side if uncertain.

Mexico is predominantly Catholic and churches are active places of worship that tourists visit extensively. Covered shoulders and knees are required in virtually all Catholic churches; many larger basilicas enforce this at the door. The Basilica de Guadalupe in Mexico City is the most visited Catholic site in the Americas and requires respectful, modest dress. Indigenous churches, especially San Juan Chamula in Chiapas, operate under community law completely separate from the Catholic hierarchy and have strict rules including absolute bans on photography, loud behaviour, and foreign religious items.

Mexico has diverse climate zones. The dry season (November to April) offers pleasant temperatures, clear skies, and the lowest chance of rain across most of the country — this is peak tourist season. The rainy season (May to October) brings afternoon showers that are often brief but can be heavy. Hurricane season (June to November) poses real risks to the Yucatán Peninsula, Quintana Roo (Cancún, Tulum, Playa del Carmen), and Pacific coast destinations like Puerto Vallarta and Manzanillo. Mexico City's high altitude keeps temperatures moderate year-round at around 15–25°C.

Mexico offers outstanding value for money when you eat and travel like a local. The menú del día (set lunch) delivers three courses for approximately 80–120 pesos (4–6 USD). Street tacos run 15–25 pesos each. OXXO stores are ideal for cheap bottled water, snacks, and basics. Always pay in pesos — vendors and some shops accept USD but at very poor exchange rates. Use the Metro (5 pesos in CDMX) and colectivos instead of taxis. National museums are free on Sundays for Mexican residents but usually charge a small fee for foreign visitors.
