Pretty much every stay I’ve been verbally asked for my number by hotel staff

whats the security risk here. Someone going to break into your room? Unlikely and why would you giving your room number increase the odds of that

its not like hotels don’t have numbers on the doors so me overhearing a guest give their number as 201 is going to materially become a factor if I wanted to charge something to room 201 by just guessing the hotel has room 201

not getting the concerns here
