What do you mean by unsigned bills in the hotel?

The act of signing a bill without paying it in real time. The hotel no longer accepts the behavior that guests only sign the bill after consumption and do not check out in real time. Generally speaking, hotels don't accept credit cards. The hotel does not sign the bill, that is, the guests who spend in the hotel, whether in the hotel room or in the hotel catering, only need to confirm and sign the bill after the consumption, and do not need to pay the bill in cash or credit card immediately.
