“Help,I can’t get out of my room”
“Try the door” says the receptionist.
“I have,but can’t get out”
“Are you sure?”
“Yes” says the blonde.“There are only 3 doors in the room.The first one is to the bathroom and the second is the ward-robe”
“So what about the third one?” says the receptionist
"That’s got a sign on the handle saying ‘Do not disturb’ "
