The way to solve the problem that the waiter doesn't know who to give the bill to is to ask the guest, observe the behavior of the guest and ask other waiters for help.

1, ask the guest. If you need to check out, you can ask the guest on the table. If the guest says he needs to check out, he can give the bill directly to the guest.

2, observe the behavior of the guests, you can observe the behavior of the guests, such as whether to take out your wallet or move a chair to leave. If the guest's behavior shows that they are ready to check out, they can hand the bill to the guest.

3. Ask other waiters for help. If you are not sure who to pay the bill to, you can ask other waiters for help. The rest of the waiters can help confirm the needs of the guests and help with the checkout.
