An airline captain was helping a new flight attendant prepare for her first overnight trip. Upon their arrival, the captain showed the flight attendant the best place for to eat and shop.

The next morning as the pilot was preparing the crew for the day’s routine, he noticed the new attendant was missing. He knew which room she stayed in at the hotel and called her up to find out what had happened to her. She answered the phone, crying: “I can’t get out of the room!”

“Why not?” asked the captain.

“There are only three doors in here,” she sobbed. “One is the bathroom, one is the closet, and one has a sign on it that says ‘Do Not Disturb’!”
