Sandeep Mukerji was on his first visit to Thailand but would leave the “Land of Smiles” with a frown and an empty pocket.

A stone’s throw from the Grand Palace in Bangkok, the 26-year-old Canadian ran into a monk in a robe. The monk told him that the attraction he was hoping to visit had been closed.

The monk then introduced Mukerji to a jewellery store instead. On the way there, three different people told him that it was the last day of a once-a-year, tax-free jewellery promotion to encourage tourism.

They said that tourists can make a lot of money by buying gems（宝石）in Thailand and selling them once at home.

Two hours later, Mukerji had spent US $ 1, 250 on a set of almost worthless jewellery in the jewellery store.

“The whole process took me by surprise. They take advantage of your greed,” he said.

In fact, Mukerji is just one of a huge number of tourists who are cheated by the promise of making a fortune. The scam（诡计）brings Thailand more than US $ 10 million each year.

Although tourist police stations have displayed posters to warn of the scam, many fresh-faced tourists still fall prey to the trick.

The police say they receive 5～10 complaints a day. Many more may not realize they have been cheated until they go back home.

That authorities say that the jewellery scam is harmful to Thailand’s image, but getting rid of the cheats is hard.

Sanit Miphan, head of the police, said the scam has been running for about 15 years but not one jewellery shop owner has been arrested.

The shops usually open for two weeks and then close. They reopen and register under a new name. What’s more, overcharging（要价过高）itself is not breaking the law.

Yet, to keep the tourism business alive, the police said they would take action against any shop receiving more than 10 complaints.
