A businessman had a tiring day on the road. He checked into a hotel and, because he was concerned that the dining room might close soon, left his luggage at the front desk and went immediately to eat.
After a leisurely dinner, he reclaimed his luggage and realized that he had forgotten his room number. He went back to the desk and told the clerk on duty, "My name is Henry Davis, can you please tell me what room I am in?"
"Certainly," said the clerk. "You're in the lobby."
