Question

Here's a brain teaser for u!
1) 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?
Please I need the correct answer with explanation.

Answer 1

She knew he was scoping the place out because if it really was his room, why wouldn't he have just used the key to get in instead of knocking?

Hope dis helps u..

Answer 2

If the room was of him then why he knocked at the door he should use keys and enter the room..
