Scams to Watch For

You step off the BTS at Saphan Taksin, and within 30 seconds a smiling Thai man tells you the Grand Palace is closed for a royal ceremony today. It’s open. He’s running the most common script in Bangkok, and it ends with you paying 50,000 baht for a pair of fake sapphires. Here’s every con targeting tourists in Bangkok, how to spot each one before your wallet takes the hit, and what to do if your guard drops.

The Grand Palace “Closed Today” Loop

You approach the Grand Palace entrance. A tuk-tuk driver or a “helpful” local by the gate flags you down. “No, no, palace closed today — Buddhist holiday, royal ceremony.” They offer to take you to another temple (usually Wat Pho, which is not closed) and then to a special gem factory where “only Thais get discount.” Fact: The Grand Palace is open every day from 08:30-15:30 except for a handful of genuine national holidays you can verify on the official website. Ignore anyone who speaks to you within 100 metres of the entrance. Walk straight to the ticket gate. If you are told it’s closed, smile, nod, and keep walking. Do not engage.

The Gem Scam – Bangkok’s Most Expensive Souvenir

This is the logical extension of the Grand Palace lie. A tuk-tuk or taxi driver takes you to a nondescript shop (often near Nana or Sukhumvit Soi 4). Inside, a friendly salesperson shows you “high-quality” gems at “factory prices.” You buy a few stones for $200–$5,000. Back home, a jeweller tells you they are colour-treated quartz, synthetic corundum, or glass. Worst case: the shop changes name weekly and refunds are impossible. Zero exceptions: never enter any jewellery or gem shop recommended by a driver. Not even to “look.” The police will not help you get your money back (more on that below).

The 20 Baht Tuk-Tuk City Tour

A tuk-tuk driver offers to take you to four temples and a market for 20 baht. You know it’s too good to be true. Here’s the math: the driver gets a commission from each stop. The first stop is a tailor (where you’re pressured to buy a cheap polyester “silk” suit), the second is a gem shop, the third a travel agent selling overpriced tours. You’ll waste two hours being sold to. After you buy nothing, the driver dumps you far from your hotel. Rule: if a tuk-tuk ride is cheaper than a bus fare (8 baht), there’s a catch. Pay metered taxi rates or use Grab/Bolt. A legit short tuk-tuk ride in Bangkok costs 100–200 baht.

Taxi Meter Scam

You hail a taxi on the street. The driver says “meter broken, only flat price 500 baht” for a trip that should cost 100 baht. Do not negotiate. Just open the door and get out. The next taxi will have a working meter. Taxis at the airport: ignore the touts inside the arrivals hall who offer “special price.” Go to the official public taxi rank on Level 1 at both BKK (Suvarnabhumi) and DMK (Don Mueang). The machine gives you a ticket with a car number. Insist the driver uses the meter. There is a legitimate 50 baht airport surcharge plus highway tolls (around 70 baht total). That’s it. If the driver refuses to start the meter, report the plate to the Airport Taxi desk inside.

Tailored Suit Pressure – “Cheap Silk” Trap

A driver or a tout on Khao San Road promises “bespoke silk suits for 1,500 baht.” You go to a small shop, pick a fabric, get measured, pay a 50% deposit. The suit arrives at your hotel two days later – it’s polyester lining, crooked stitching, and the colour is wrong. The shop has no phone number. Bangkok does have good tailors (Crown Tailor, Narin Couture), but they don’t solicit on the street. Legit bespoke starts around 8,000 baht. If a deal sounds too cheap, skip it. Never hand over a deposit without a receipt and a shop address you can verify.

Bar and Club Bill Padding

You sit at a rooftop bar near Soi Cowboy or in Khao San. No prices on the menu. You order two “Jack and Coke.” The bill arrives: 5,000 baht. The drinks were laced with cheap spirits and the ice costs 300 baht per cube. How to avoid: only drink at places where drink prices are clearly posted on a menu. Hotel rooftop bars (Vertigo at Banyan Tree, Above Eleven) are safe and fairly priced. In neighbourhoods like Thong Lo, most venues are honest. If you get a suspicious bill, refuse to pay the inflated amount and offer to call the Tourist Police (1155). Most bars will back down.

Friendship Bracelet / Flower Garland Con

Around Khao San Road and Asok BTS, a “student” or “monk” approaches you, ties a bracelet or a jasmine garland on your wrist, and then demands a “donation” of 200 baht. Some will pickpocket you while they tie it. Don’t let anyone touch your wrist. If it’s already on, untie it, hand it back, and walk away. Do not pay.

Massage Parlour Bait-and-Switch

You walk into a massage shop on Sukhumvit Soi 11 with a traditional sign. The receptionist quotes 300 baht for a foot massage. After 45 minutes, the therapist asks if you want “happy ending.” You say no. She leaves. The manager then presents a bill for 1,500 baht “extra service fee.” Clarify at the door: ask for the price list and be clear you want a traditional Thai massage only. If they pressure, leave. Reputable chains (Health Land, Let’s Relax, Oasis) are safe. Budget for a decent massage instead of risking a dodgy shop.

Police Extortion – Fake Fines for Vaping / Cannabis

Thailand has confusing laws. Vaping is illegal (in theory) and cannabis is legal for medical but not for recreational public use. Fake police (or real ones in uniform off duty) pull you over, claim you’re violating the law, and demand a “fine” payable in cash on the spot — no receipt. Real fines must be paid at a police station with an official receipt. What to do: politely ask for the name and badge number, say you want to go to the station to pay. Offer to call 1155 (Tourist Police, 24h English). Most scammers will wave you off. If they persist, dial 1155 immediately. Under no circumstances hand over cash to someone on the street.

ATM Skimming and DCC

Skimmers are common on standalone ATMs near Khao San, Sukhumvit Soi 11, and Patpong. Only use ATMs inside bank branches (Bangkok Bank, Kasikorn, SCB) during opening hours. Check the card slot for loose parts. Cover your PIN hand. When the machine asks if you want to convert to your home currency (Dynamic Currency Conversion), always select “Charge in Thai Baht” or “Continue without conversion.” DCC adds 3-7% in hidden fees for zero benefit. For more on fees and cards, see the money guide.

Pickpocketing and Bag Slashing

Bangkok is not a high-risk city for pickpocketing compared to Rome or Barcelona. The only real danger is on packed BTS Skytrain cars during rush hour (07:30–09:00 and 17:00–19:30). Thieves use a razor blade to slash the bottom of a backpack or a side bag while the train sways. Keep your bag in front of you, zipped, with valuables at the bottom. Never keep your wallet in a back pocket on a packed Skytrain. Pickpockets also work wet markets (Chatuchak on weekends). Carry only what you need.

What to Do If You’ve Been Scammed or Robbed

Tourist Police hotline 1155 – 24 hours, English spoken. They can come to you or advise by phone. They are genuinely helpful for taxi disputes, bar bill padding, and lost passports.
Card stolen or cloned: call your bank immediately (within 60 minutes for zero liability in most cases). Use the hotline numbers on your card, or ask the hotel front desk to help you call.
Report online: touristpolice.go.th allows you to file a report electronically. Save the reference number.
Lost passport: go to your embassy and get an emergency passport. For police report, visit Tourist Police station on Ratchadamnoen Klang Road (near Khao San) or call 1155.
Gem scam victims have very little recourse. Filing a complaint with the Tourist Police may get a visit to the shop, but if the shop has moved or the business is registered to a shell company, you’re unlikely to recover funds. This is why prevention matters most.

One More Thing – The Water and the Plugs

Since we promised no generic filler, just a quick operational point: tap water in Bangkok is technically potable but not recommended for foreigners’ stomachs. Drink bottled. Plug type: same as the US (A/B) but with 220V. Most modern electronics handle 110-240V. Get an adapter if your charger is two-pin flat.

And if you see someone selling a “VIP pass to the Grand Palace” outside the gate – it’s a scam. The ticket is 500 baht. You don’t need a guide. Now go enjoy Bangkok without getting taken.
