During my stay at an expensive hotel in New York City, I woke up in the middle of the night with an upset stomach. I called room service and ordered some soda crackers. When I looked at the charge slip, I was furious. I 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 to the other end cooly explained. “I believe you are complaining about your room number.”
