Con artists in Beijing befriend tourists and, after a small chat, offer to take them to a traditional tea ceremony. This is not presented as a sales pitch by a tourism. Instead, the con artists act as if the ceremony is a regualr part of their daily lives and the victim is being invited along.
The tourists feel as if they are been allowed to participant in a very authentic experience that everyday Chinese people do.
Once they arrive at the ceremony, they drink a small amount of tea but are not shown a menu. At the end of the ceremony, the tea house owner presents the group with a large bill, perhaps $50 per head. Each of the con artists takes out the equivilant of $50 and pays the bill. The victim, not wanting to look cheap or stupid, does the same thing.
The con artists then share the money with the tea house owner.
