Considering its size, Bangkok is a relatively safe city. But you should be smart: don't wander down dark alleyways alone and always protect against theft (use a hotel safe and conceal valuables). You are more likely to be conned out of your money than have it forcibly removed. Be wary of friendly strangers offering touring advice: this is usually a long and costly introduction to the gem scams, in which travellers are sold worthless jewels and jewellery for a king's ransom. Tuk tuk drivers offering THB 10.00 rides are another gateway into the scam scene: tailors that overcharge, jewellery stores selling costume as heirlooms, etc. Ignore anyone who says that the Skytrain or major attractions are closed for a holiday or cleaning. This is yet another popular start to the gem scam. More likely to happen in the girlie-bar world are druggings with cigarettes, food and drink followed by a house cleaning of valuables.
