Cash, Card, ATMs & Tipping in Bangkok

You’re about to hand over a 1,000-baht note for a 120-baht bowl of noodles and the vendor stares at you like you just insulted their ancestors. That’s because you just did — not out of malice, but because nobody here carries 1000s for small purchases, and now they have to break it, which is annoying. Welcome to Bangkok’s cash-first reality. Here’s how not to get burned by ATMs, exchange booths, and the tipping scripts that tourists always misread.

Currency basics & the dominance of cash

Thailand uses the baht (THB, symbol ฿). At the time of writing, one US dollar buys roughly 35 baht, but check SuperRich Thailand for live rates before you leave the hotel. Bangkok is a cash city in ways that surprise first-timers. Street food, taxis, tuk-tuks, motorbike taxis, market stalls, and even 7-Eleven purchases under 200 baht expect cash. The 7-Eleven counter clerk will not break a large note with a smile; they’ll do it but you’ll see the eye roll.

Cards are accepted at malls like Siam Paragon, EmQuartier, and CentralWorld, chain restaurants, big hotels, supermarkets (Tops, Gourmet Market), and BTS SkyTrain ticket machines (but only at stations — the machines take coins and notes). Apple Pay and Google Pay are slowly showing up at major retailers but are unreliable. Always carry enough cash to cover a day’s basics: food, transport, and a stray water bottle.

ATMs: fee traps and how to dodge them

Every ATM in Thailand charges a 220-baht fee per withdrawal for foreign-issued cards. This fee is flat regardless of the bank (Kasikorn, Bangkok Bank, SCB, Krungsri — all 220฿). The only exception is Aeon Bank ATMs, which charge 150฿ — still high but better. Aeon machines are less common, but you can find them in some malls (e.g., near the food court at Terminal 21) and near BTS stations.

The math is simple: withdraw larger amounts less often. A single 20,000-baht withdrawal at 220฿ fee pencils out to a 1.1% fee. If you pull only 3,000฿, that’s a brutal 7.3% fee. Do the bigger withdrawal and stash the cash in your hotel safe.

When the ATM asks: “Do you accept the conversion?” — always decline. This is Dynamic Currency Conversion (DCC), a scam that pins a terrible exchange rate. Choose “Continue without conversion” or “Charge in THB”. Your bank’s rate will be better.

Where to exchange cash for the best rate

Airport exchange counters are the worst. Rates at Suvarnabhumi are 3-5% below market. If you have to arrive with cash, change only enough for a taxi and a meal, then hit the city. The gold standard is SuperRich Thailand, a chain with multiple branches. The original green SuperRich booths (older design) and the orange ones both offer near market rates. Top branches:

BTS Asok — inside the station near exit 4, extremely convenient.
Pratunam — right off Soi Petchburi 19, open daily 9 am–6 pm.
Silom — near Sala Daeng BTS, Soi 3.

Bring your passport. Yes, even for a simple exchange — it’s required by law. Rates are also good at TT Exchange (also in Asok) and Vasu Exchange near the Indian temples in Silom. Never use street-side exchange booths that quote “no commission” — they bury the spread.

Cards: what works and what doesn’t

Visa and Mastercard are widely accepted wherever cards are taken. American Express is often rejected or incurs a 2-3% surcharge. Don’t rely on AMEX. The chip-and-PIN system is standard: you insert the card and enter a 4-6 digit PIN. Contactless is less common. Merchants in malls and chain restaurants expect a PIN even for ‘credit’ transactions; if your card is signature-only, tell them, and they’ll sometimes print a slip, but it’s awkward.

If you’re using a foreign card at a hotel or high-end restaurant, they may ask to see your passport for verification — standard. Apple Pay/Google Pay works at a growing number of terminals (e.g., 7-Eleven, Central department stores, some Starbucks), but not everywhere. Don’t assume you can tap-and-go all day.

Tipping: the actual etiquette, not the rumour

Tipping is not mandatory or expected in Thailand. The culture of gratuity does not exist as in the US. Here’s the realistic breakdown:

7-Eleven cashier — zero. Do not leave coins. They don’t have a tip jar.
Taxi driver — round up to the next 10 or 20 baht if you’re feeling generous. 57฿? Give 60. 94฿? Give 100. They won’t chase you for more.
Tuk-tuk driver — tip only if they helped with heavy bags. Otherwise the price is already negotiated.
Restaurant — check the bill for a 7% VAT and possibly a 10% service charge. If service charge is included, no tip needed. If not, leaving 5-10% is a nice gesture, but not expected. Thais rarely tip in casual restaurants.
Massage/Spa — 50–100 baht per hour is standard if you enjoyed the service. Hand it directly to the therapist, not the front desk.
Tour guide or driver on a day trip — low end: 100 baht; high end: 300 baht per day per person. But only if they were good. No guilt if you skip.

If a restaurant adds a service charge on a bill but then you see a separate “box for tips” at the register — that’s for the staff pool. You can drop coins, but nobody judges you for not.

Bargaining: where it works and where it backfires

Chatuchak Weekend Market, street stalls, and tuk-tuk rides: yes, you bargain. Department stores, 7-Eleven, food courts: absolutely not. The rule of thumb: start at around 50% of the asking price, settle at roughly 70%. If you’re buying multiple items, bundle them for a better deal. Walk away if the price doesn’t move — that’s the correct script.

But beware: some items at Chatuchak are already marked ‘fixed price’ (usually on a sign) — respect that. Also, sellers may give you a lower price in Thai if they hear you speak the language. If you’re bargaining, stay polite and smile; aggressive haggling is rude and rarely works.

The foreigner price tax

In tourist-heavy areas (Khao San Road, Patpong, Soi Cowboy), expect a 20–50% markup on prices for foreign faces. A t-shirt that costs 150 baht a block away sells for 350 at Khao San. A tuk-tuk ride from Khao San to Asok might be quoted 400 baht when the real fare is 150. Walk one street away from the main tourist strip and sudden everything is cheaper. Same applies to massages and street food: eat where locals eat, not where the hostel owner sends you.

Hidden costs on your bill

Restaurants in malls and hotels often add a 10% service charge and 7% VAT automatically. This is legal and normal — it appears on the menu (fine print) and the bill. No extra tip needed. But watch for bar bill padding: some bars in Nana and Patpong add drinks you didn’t order. Always check the itemized bill, and never let the server take your card away without seeing the receipt. For more on that, see our Bangkok scams guide.

VAT refund for tourists

If you spend at least 2,000 baht in a single store that offers VAT refund (look for the “VAT Refund for Tourists” sign), ask for a P.P.10 form. You need a minimum total of 5,000 baht across all such receipts to claim at the airport. Go to the Customs Inspection Office (before check-in) at Suvarnabhumi or Don Mueang, present goods and receipts, get a stamp, then proceed to the VAT refund counter past security. The refund is about 6–7% (after a 100-baht fee). Don’t check in first — customs will want to see the items. For more on navigating the airport at odd hours, check our 24-hour services page.

Tap water and other daily costs

Do not drink tap water in Bangkok. Bottled water costs 14 baht for a 1.5-liter bottle at any 7-Eleven. Your hotel might provide free drinking water in the lobby or a dispenser. Ice in restaurants is made from filtered water (blue plastic bags) and is safe. Street food ice cubes are factory-produced and also safe.

Other hidden costs: airport tax is included in your airfare (no extra). Public transport (BTS, MRT) is cash only — no cards accepted at ticket counters, though some BTS machines now take credit cards (but not all). Taxi meter starts at 35 baht; a trip across central Bangkok runs about 80–150 baht. Tollway fees (expressway) are extra and the driver will expect you to pay those in cash.

Emergency cash and lost card

If you lose your card or run out of cash, most major banks can issue a card replacement but it takes days. Western Union is widespread — send money to yourself and pick up cash at a branch (e.g., at Asok or Siam). For after-hours help, our 24-hour page lists all-night pharmacies and Western Union locations. The tourist police hotline is 1155 for lost/stolen passport emergencies.
