Airline captain

An airline captain was helping a new blonde flight attendant prepare for her
first overnight trip. Upon their arrival, the captain showed the flight
attendant the best place for airline personnel to eat, shop, and stay overnight.
The next morning as the pilot was preparing the crew for the day's route, he
noticed the new stewardess was missing. He knew which room she was in at the
hotel and called her up to ask what happened to her. She answered the phone,
crying, and said, "I can't get out of the room!" "You can't get out of your
room?"; the captain asked. "Why not?" She replied, "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'!"
