A customer was continually bothering the waiter in arestaurant; first, he'd asked that the air conditioning beturned up because he was too hot, then he asked it be turneddown 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 secondcustomer 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."
