A man went to a hotel and walked up to the front desk to check in. The woman at the desk gave him his key and told him that on the way to his room, there was a door with no number that was locked and no one was allowed in there. She explained that it was a storeroom, and that it was out of bounds. She reminded him of this several times before allowing him upstairs. So he followed the instructions of the woman at the front desk, going straight to his room, and going to bed. At this point he decided to consult her for more information. She sighed and said, "Did you look through the keyhole?"
