A customer was bothering the waiter in a restaurant.

First he asked that the airconditioning be turned up because
he was too hot, then he asked it be
turned down cause he was too cold and so on for about half an
hour.

Surprisingly, the waiter was
very patient, he walked back and forth 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"
