A joke

A customer was continually bothering a waiter in a restaurant. First he asked that the air conditioning be turned up because he was too cold then he asked it be turned down because he was too hot, and so on, for about half an hour. Surprisingly, the waiter was very patient, he went back and forth at every request and never once got angry. So finally, a second customer asked him why he didn`t throw out the pest. "Oh I don`t care," said the waiter with a smile.
"We don`t even have an air conditioner"
