What does the hotel mean by booking a room?

Duel, expiration, expectation, consent, appropriateness and sufficiency. It means that as a cashier, you will have some reserves in your hand, such as change or refund.

For example, if you take over on a business day, you have 1 0,000 yuan in your hand. Later, a guest checked out and needed to refund the deposit, 500 yuan. Then you only have 9500 left in your hand. Then this poor 500 yuan is a duel. Before leaving work, submit the relevant documents of this refund behavior, such as deposit slip and refund slip, to the finance department for review. And fill out the duel form in duplicate. Put a couplet with your 9500 to show the whereabouts of 500 yuan. The other one is for the hotel cashier. After the audit is completed the next day, I will inform you to take your refund slip to the finance department to get it back to 500 yuan.
