Complaining Customer and Waiter

A customer was continually bothering the waiter in a restaurant. First, he asked that the air conditioning be turned up because he was too cold, then he asked that it be turned down because he was too hot, and so it went for about a half an hour.

Surprisingly, the waiter was very patient. He walked back and forth and never once got angry. Finally, a second customer asked the waiter 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."
