I'm the hotel receptionist, checking in and checking out. It's time for the guest to renew his stay, and then he said that he would pay later and the front desk would handle the renewal.

Looks like you're new at the front desk. From what you said, I judge that the front desk of your hotel doesn't charge a deposit, and guests only need to pay the room rate, right? I tell you, as a front desk, you should always remember one thing, the principle of "having money and housing, but not having money and housing". Maybe what I said is a little unpleasant, but that's the truth, otherwise you will lose. As you said, it is normal that I often meet guests who check out late. If the guest fails to check out after the deadline, he will say that he will pay later. If there is no deposit or the deposit is not enough, you should tell the supervisor on duty or AM at the first time, then hang up the guest room and charge half a day's rent (no check-out). Generally, the Chinese system at the front desk has this menu. Let the room stop skipping time. Before 18: 00 pm, if the guest doesn't come to the front desk to continue his stay, then call the room. If the guest is not here or doesn't answer all the time, inform HSKP to go to the room to check if there is any luggage. If there is no luggage, then tell the supervisor on duty or AM, and then do room C/O directly. In this way, you won't lose money.
