Air Conditioning

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

Surprisingly, the waiter was very patient, walking back and
forth and never once getting angry. So finally, a second
customer asked why didn't they just throw out the pest.

"Oh, I don't care," said the waiter with a smile. "We don't
even have an air conditioner."
