A woman is sitting in her hotel room when there is a knock at the door. She opened the door to see a man whom she had never seen
before. He said "oh I'm sorry, I have made a mistake, I thought this was my room." He then went down the corridor and in the elevator. The woman went back into her room and phoned security. What made the woman so suspicious of the man?
The woman called security as the man must of had his on key/keycard and it should have the number to the correct room. He also does not need to knock on the door unless he had already known someone was in there. he should his own key/keycard
