Tipping
🔥Tipping is mandatory in practice — 18-22% at sit-down restaurants is the current norm, as servers can legally be paid as little as $2.13/hr in base wages.
⛔Failing to tip at a sit-down restaurant is a serious social transgression in the US — servers rely on tips as their primary income, not as a bonus.
Full guide →
Tip 10–15% at sit-down restaurants if service was good. Check for a service charge already on the bill. No tipping expected at pubs when ordering at the bar.

Public Transport
The US has no national public transport network — outside of a handful of major cities, a rental car is essential for getting around.
⛔Renting a car is almost always required outside of major cities — attempting to explore national parks or suburban areas without one will severely limit your trip.
Full guide →
Use contactless card or Apple/Google Pay on London's Tube and buses — no need for an Oyster card. Outside London, trains are expensive; book far in advance.
⛔Walk-up train fares in the UK are among the most expensive in Europe. Always book in advance for long-distance trips — same-day tickets can cost 3–5x more.

Tourist Healthcare
US healthcare is the most expensive in the world — a single emergency room visit can cost USD 3,000-10,000 or more without insurance, making comprehensive travel insurance absolutely mandatory.
⛔Do not rely on being treated and sorting out payment later — US hospitals will pursue medical debt aggressively, including through collection agencies and legal action.
Full guide →
The NHS provides emergency care to all. EU citizens use the EHIC/GHIC card. Non-EU tourists are charged. Travel insurance is recommended for all.
⛔NHS A&E wait times can be extremely long (4–12 hours) for non-life-threatening conditions. For minor issues, use urgent treatment centres, pharmacists, or NHS 111 instead.
Full guide →
Local Laws
Laws vary significantly from state to state — cannabis, gun ownership, and alcohol rules that are legal in one state can be criminal offences in another.
⛔Cannabis is illegal under federal law regardless of state legality — do not carry it through airports, across state lines, or onto any federal land including national parks.
Full guide →
UK laws are generally familiar to Western tourists. Note: knife-carrying laws are strict, drugs are illegal, and social media harassment can be prosecuted.

Emergency Numbers
Dress Code
The US is extremely casual — there are virtually no enforced dress codes in public, and Americans dress far more informally than European standards.
Full guide →
The UK is very relaxed about clothing. Dress smart-casual for upscale restaurants and clubs. Carry a waterproof — rain is frequent and unpredictable.
Full guide →
Alcohol Rules
The drinking age is 21 nationwide with no exceptions, and ID is checked rigorously — even visitors who are clearly middle-aged are routinely asked for ID.
⛔Purchasing alcohol for anyone under 21 ('contributing to the delinquency of a minor') is a criminal offence — do not buy alcohol for younger members of your travel group regardless of the legal drinking age in your home country.
Full guide →
Drinking age is 18. Alcohol is sold at supermarkets, off-licences, and pubs. Drinking in public is legal in most areas. Pub last orders typically at 11pm.
⛔Drinking on London Underground (Tube), Overground, and Transport for London buses is banned by law. You can be removed from the service.
Full guide →
Bargaining Culture
Bargaining is not part of American retail culture — prices in shops are fixed, though negotiation is expected when buying cars, and is possible at garage sales and antique shops.
Full guide →
Fixed prices everywhere in retail. Bargaining is acceptable at market stalls, car boot sales, and with private sellers. Some room for negotiation on large purchases.
Full guide →
Photography Rules
Photography in public spaces is broadly protected under the First Amendment — you have the legal right to photograph anything visible from a public area, including police officers on duty.
⛔Photographing or filming inside military bases, classified government facilities, or nuclear power plants is illegal and can result in immediate detention — respect all posted signage.
Full guide →
Photography in public spaces is broadly legal in the UK. No law against photographing in public, but private properties and some government sites are restricted.
Full guide →
Sunday & Holiday Hours
Most US retail operates 7 days a week, but Thanksgiving and Christmas cause widespread closures, and some states restrict Sunday alcohol sales under blue laws.
Full guide →
Large shops open shorter Sunday hours (typically 10am–4pm or 11am–5pm). Pubs and restaurants normal hours. Bank Holidays see widespread closures.
⛔On Bank Holidays (especially Christmas and Easter), most shops and services close. Train and bus services run on a reduced 'holiday timetable' — check in advance.
Full guide →
Taxi & Rideshare
🔥Uber and Lyft operate in virtually every US city and are the default way to get around without a car — traditional taxis still operate mainly at airports and in NYC.
⛔Surge pricing during large events (concerts, sports games, New Year's Eve) can multiply fares by 3-5x — consider public transport, pre-arranged taxis, or walking short distances to avoid the worst surges.
Full guide →
Uber, Bolt, and Ola all operate across the UK; London's iconic black cabs are metered and trustworthy but expensive.
⛔Never get into an unlicensed minicab. Touts outside nightclubs and train stations sometimes offer rides — these drivers are unregulated and passengers have been assaulted.
Full guide →
Water Safety
🔥Tap water is safe to drink throughout the US — it is one of the most tightly regulated drinking water systems in the world and bottled water is largely unnecessary.
Full guide →
Tap water throughout the UK is excellent quality and completely safe to drink straight from the tap.
Full guide →
ATMs & Cash
Card payments are accepted almost everywhere in the US, but cash is still useful for tips, small vendors, and street food — ATM fees of USD 2-5 per withdrawal are common.
⛔Airport ATMs and hotel ATMs charge the highest fees — use a major bank's ATM (Chase, Bank of America, Wells Fargo) or a zero-fee international card instead.
Full guide →
UK ATMs are widespread and free at supermarkets and post offices; contactless payments up to £100 are the norm but some small venues still require cash.
⛔Shoulder surfing at busy ATMs (especially on the London Underground) is a real risk — shield your PIN and be aware of your surroundings when withdrawing cash.
Full guide →
SIM Card & Internet
🔥T-Mobile tourist SIM plans from USD 15-35/month offer the best value for visitors, while an Airalo eSIM is the most convenient option if your phone supports it.
⛔Do not rely on cellular coverage in national parks or remote wilderness areas — download offline maps and emergency contact numbers before entering areas with limited signal.
Full guide →
Buy a UK SIM at the airport or Argos for instant data; Three's £10 tourist SIM offers excellent value, and Airalo eSIMs work well before you land.
⛔Coverage in the Scottish Highlands, Snowdonia, and remote parts of Northern Ireland can be very poor or nonexistent — download offline maps before heading into rural areas.
Full guide →
Electricity & Plugs
🔥The US uses Type A and Type B flat-pin plugs at 120V/60Hz — visitors from Europe, Asia, Australia, and Africa need both a plug adapter and possibly a voltage converter.
⛔Plugging a 220V hair dryer or appliance into a 120V US outlet without a voltage converter will damage the device — always check the voltage rating before plugging in.
Full guide →
The UK uses Type G (3-pin square) plugs at 230V/50Hz — virtually all visitors except those from Ireland need an adapter.
Full guide →
Scams to Avoid
Tourist scams in the US are moderate risk — timeshare presentations, fake ticket sellers, and overpriced 'official' souvenirs near major attractions are the most common pitfalls.
⛔Online vacation rental scams are increasingly common — always book through established platforms (Airbnb, VRBO) and be suspicious of deals requiring direct bank transfer or payment outside the platform.
Full guide →
The UK has a low scam culture overall, but London tourists should watch for ticket touts, fake gold rings, aggressive charity collectors, and pickpockets on the Underground.
⛔The 'dropped gold ring' scam is common near major London attractions — someone 'finds' a ring at your feet and offers it to you, then demands money. Walk away immediately.
Full guide →
Crime & Safety
Tourist areas in major US cities are generally safe, but gun violence rates are higher than comparable developed countries and specific neighborhoods in some cities carry significant risk.
⛔Gun violence in the US is statistically more prevalent than in other comparable countries — while the risk to tourists is low, being aware of your environment and knowing the location of exits in public venues is a reasonable precaution.
Full guide →
The UK is generally very safe for tourists; the main risks are pickpocketing on the London Underground and avoiding a small number of rough urban areas after dark.
⛔Pickpockets operate on the London Underground, particularly on tourist-heavy lines. Be especially vigilant at busy stations like King's Cross, Oxford Circus, and London Bridge.
Full guide →
Cultural Etiquette
Americans are informal, friendly, and quick to use first names — small talk with strangers is normal, 'How are you?' is a greeting not a real question, and enthusiasm in service is expected.
Full guide →
Queuing is sacred, 'sorry' is said constantly, and pub etiquette means ordering at the bar — understanding these unwritten rules makes a huge difference.
Full guide →
Language Basics
English is the sole working language of the US, and proficiency in English is assumed for all services — though Spanish is widely spoken in Florida, the Southwest, and parts of major cities.
Full guide →
English is spoken everywhere, but British vocabulary differs from American English and strong regional accents can be genuinely challenging for visitors.
Full guide →
Beach & Swimming
The US has world-class beaches but rip currents are the leading danger at ocean beaches — always swim between the flags and never ignore beach closure signs.
⛔Rip currents are responsible for the majority of ocean beach drownings in the US — they are invisible from shore, can occur on calm-looking days, and should be taken seriously even by strong swimmers.
Full guide →
UK beaches are beautiful but water is cold year-round; RNLI lifeguards patrol popular beaches and rip currents are the main swimming danger.
⛔Rip currents claim lives on UK beaches every year. If you see red flags or a red and yellow flag with a diagonal red stripe, do not enter the water.
Full guide →
Driving Rules
Drive on the right side of the road; an international driving permit plus your home licence is valid in most states; a rental car is essential for exploring beyond major cities.
⛔Distracted driving laws (no hand-held phone use while driving) are enforced in most states and fines are substantial — use hands-free Bluetooth or pull over to use your phone while driving.
Full guide →
Drive on the left; speed is in mph not km/h; central London has a daily congestion charge; and motorway etiquette requires keeping left except when overtaking.
⛔There is no right turn on red in the UK. Speed cameras are widespread on all road types and fines are issued automatically by post — speeding is enforced very effectively.
Full guide →
Restaurants & Food
American regional food culture is extraordinarily diverse — from NYC pizza and Texas BBQ to New Orleans Creole and California cuisine — with portions that are universally enormous.
⛔Tipping 18-20% is expected at all sit-down restaurants — the listed menu prices do not include the tip, so factor this into your budget when planning dining costs.
Full guide →
VAT is included in displayed prices; service charge may be added separately; and British food culture spans the Full English, fish and chips, Sunday roast, and a world-class curry scene.
Full guide →
Religious Site Etiquette
The US has a rich diversity of religious sites that are generally very welcoming to visitors — dress modestly, be quiet, and follow the lead of worshippers.
Full guide →
The UK is highly diverse with active mosques, Sikh gurdwaras, Hindu temples, and historic churches — most welcome respectful visitors; remove shoes at mosques, gurdwaras, and Hindu temples.
Full guide →
Weather & Best Time
The best time to visit most of the continental US is May-June or September-October, avoiding the extremes of summer heat and winter cold — though the ideal timing varies enormously by region.
⛔The Southwest desert heat from June to September is genuinely dangerous — heat stroke and dehydration kill hikers every year in places like Death Valley and the Grand Canyon; always carry several litres of water and plan hikes for early morning.
Full guide →
June to August offers the warmest weather and longest days; rain is possible in any month so always carry a waterproof layer.
Full guide →
Money-Saving Tips
The US can be expensive, but happy hour specials, national park annual passes, eating at food trucks, and booking domestic flights on Tuesdays can significantly cut costs.
Full guide →
London's national museums are all free, supermarket meal deals offer great-value lunches, and railcards give 30% off train travel across the country.
