Bob was staying at an expensive hotel in New York City, and woke up in the middle of the night with an upset stomach.

He called room service and ordered some soda crackers. Later when he looked at the charge slip, he was furious. Bob called room service and raged, "I know I'm in a luxury hotel, but $11.50 for six crackers is ridiculous!"

"The crackers are complimentary," the voice at the other end coolly explained. "I believe you are complaining about your room number." (from Cybersalt.org)
