I can't get out

This was to be the new blonde（金发女郎） flight attendant's first overnight trip, so the Captain was showing her the best place for personnel to eat, shop and stay overnight. The next morning, as he was preparing the crew for the day's flight, he noticed the new flight attendant（空中服务人员） was missing. Since he knew which hotel room she was staying in he called her to find out what had happened.

Crying, she answered the phone and said, "Help, I can't get out of the room!" "What do you mean, you can't get out of the room?" the Captain asked.

"Well I can only find three doors," she sobbed（啜泣，呜咽） . "One is the bathroom, one is the closet and the other one has a sign on it that says, 'Do Not Disturb'!"
