How to deal with the large amount of cash left by the guest room safe? !

This situation must be caused by the room attendant's inadequate rounds. As the AM on duty, after receiving the notice, he went to the room with the housekeeping manager and the security manager to count the money, then deposited it in the hotel safe, took the initiative to contact the last group of guests and communicated with them politely. If the guest says he left it, please tell him the password and the specific amount of the room safe. Try to open the safe with the password he said. Of course, the handling of the whole incident should be written in the lobby log in detail.
