Thailand has had enough of foreign tourists behaving badly

Viral misbehaviour, crimes and foreign-ownership scandals are exhausting the patience of a country famous for its hospitality

Handlers at his Samut Prakan Crocodile Farm & Zoo have long thrilled onlookers by coaxing tips from the audience and carefully placing the money into the mouths of animals capable of taking off an entire hand.

The crocodiles at this open-air, fan-cooled throwback to 1980s showmanship still take their tips at the end of every show. But these days, the notes are almost all Thai baht, handed over by Thai visitors. The busloads of overseas tour groups have largely disappeared.

Tourism accounts for roughly one-fifth of the Thai economy, from the five-star resorts of Phuket and Koh Samui to the jet-ski operators and massage parlours of Pattaya.
