Another blonde one ..

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'!"
