One customer continually bothered his waiter. He’d ask for the air conditioning to be turned up because he was too hot, then he’d ask for it to be turned down because he was too cold. This continued for almost half an hour.
The waiter was extremely patient and walked back and forth, never once getting angry. Finally, another customer asked why the restaurant didn’t just ask the other customer to leave.
“It doesn’t bother me,” the waiter said, smiling. Then he leaned over and whispered, “We don’t even have air conditioning!”
