No! The response is definitely no!
A normal tea house of coffee shop will never attract customers in this way. This is a typical travel trap, and travelers, especially foreigners will always end up with being ripped off hundreds of Dollars !
The scenario is that you will meet someone on the street. He speaks simple English and seems very warm-hearted. He says he is an art student and there is an exhibition of his school, and it is FREE. You are taken to a shabby hotel on a narrow and back lane, and you find there is no art exhibition but some bruisers force you to buy things you don't want.
Another situation will be that a nice girl comes to talk to you on roadside. She says she is an English major student and she and some classmates want to practice oral English. At first, you will have a pleasant conversation. Then she invites you to a nearby tea house or coffee shop to meet her classmates. No one shows and she will ask you to order some tea or coffee first (she may use some tricks to make you order expensive foods), then she excuses herself and go to the bathroom. After waiting for 20 minutes, you realize something goes wrong. However, you have to pay for the tea or foods if you want to leave. The prices are usually hundreds times of normal prices.
