Didnt get ripped by a BG, but i made the mistake to let some money on the table in my room when going to diner.

coming back to my room i realized that the room service must have been in and some money was missing.It was not much , about 1500-2000. I think the room maid thought i dont realize it if she does not take all. I did not go to the hotel manager as it was my fault.Normally I always use the hotel safe and try to take hotels with safe in the room additional.
