On the beaches of Chaweng and Lamai, the ‘Jet Ski Mafia‘ is on the prowl for gullible tourists who love water sports. Hre's how it works: you hire a jet ski on the beach, you have your fun on the water and then return the jet ski to the vendor. The vendor then claims that it has been damaged. A disagreement between you and vendor erupts (and with the help of the vendor's friends) you are bullied into paying for damages that already existed. Vendors can become very threatening and aggressive towards customers - so beware!
"Ah ha!" you think "I'll take photos of the jet ski before I take it out to record existing damage". That doesn't work either, because the vendor may cover up the damage with water-based paint. The paint washes off when you use the jet ski. Your photos may actually prove you're responsible for the damage.
Many of the popular beach spots in Koh Samui are also home to groups of young children, sometimes no older than five or six years old. Everyone loves a game of Connect Four with kids, but this challenge will end up being a little worse on your wallet! The kids will often bet 100 or 200 baht per game...to begin with. And they will even let you win the first couple of games. But be warned - these kids are highly skilled at this game and they know how to hustle! They play it for hours on end and know every combination imaginable, so no matter how skilled you think you are - give in! Your wallet will thank us later.
