Joke: Airconditioner

A patron at a restaurant was continually bothering the waiter about the air conditioning. First he would ask for the air conditioning to be turned up because it was too hot, then he would ask it be turned down because it was too cold. This went on for about a half an hour. To the surprise of the rest of the customers, the waiter was very patient, walking aback and forth and very pleasant. So finally a customer asked; "why don’t you just throw out the pest?"
“Oh, I don’t care,” said the waiter with a grin, we don’t even have an air conditioner.”
