1. The Gem/Coffee Scam (Thailand, Vietnam)
A tuk-tuk driver offers a "free tour." You end up at a shop where aggressive salespeople sell overpriced gems, jewelry, or coffee.
**Avoidance:** Don't take "free" tours from tuk-tuk drivers.
2. The Jet Ski Damage Scam (Thailand)
You rent a jet ski. Upon return, the owner points out pre-existing "damage" and demands €500-1,000.
**Avoidance:** Take detailed photos/video before renting. Use reputable rental companies recommended by hotels.
3. The "Temple is Closed" Scam (Thailand, Cambodia)
A friendly local says the temple/museum is closed. They offer to take you to an "alternative" — which is a shop.
**Avoidance:** Check official hours online. Walk to the entrance.
4. The Bus Scam (Vietnam)
You book a "sleeper bus" through your hotel. The bus is overbooked, late, or drops you at a "partner hotel" far from the city center.
**Avoidance:** Book through reputable companies (TheSinhTourist in Vietnam, 12Go.asia).
5. The Visa Overcharge (Cambodia, Laos, Vietnam)
Officials or "helpers" at border crossings charge extra for visas.
**Avoidance:** Know the official visa fee before arrival. Don't pay "helpers."
6. The Tailor Scam (Thailand, Vietnam)
You order custom clothing, pay 50% deposit. The quality is terrible or items are never delivered.
**Avoidance:** Use well-reviewed tailors. Never pay more than 30% deposit. Get delivery dates in writing.
