Me just a few minutes ago (real life, just the room number is not real):
At the reception:
Me: Sorry, my key does not seem to work anymore.
Reception: What is your room number, sir?
Me: 683
Reception: Mr. Halbheer?
Me: Yes
Reception: Let me give you a new key
I understand: A scammer would have answered with “no” if he would not be me. Everything else would have been unfair.
