The restaurant checkout has a single two-couplet: the first couplet is the financial couplet and the second couplet is the guest couplet.

when a guest asks to settle the bill, the cashier prints out a temporary statement according to the desk number reported by the hall staff, who should check the bill first and then sign the name, and then settle the bill with the guest. If the staff in the hall doesn't sign, the cashier should remind them to sign.

if the guest pays the bill now, the hall staff should take the two bills back to the cashier for summary, return the second bill to the guest, and keep the first bill to the cashier.

if the guest pays the bill, the hall staff will hand over the guest's bill voucher to the cashier to handle the bill, and then both bills will be handed over to the cashier for processing.

when a guest presents a discount card (or a discount is given to the guest by the hall manager) at checkout, the hall manager should submit the discount card (or the manager's signature) and two bills to the cashier for discount according to the procedure. If the hall manager only submits one bill to the cashier, the cashier can not handle it.
