[speaker001:] Bill, please.
[speaker002:] Please wait a moment... here is the bill. Please check it.
[speaker001:] Excuse me, what's this item for?
[speaker002:] For three bottles of Tsingtao beer.
[speaker001:] But we've can canceled one bottle.
[speaker002:] Oh, I'm sorry. Let me go back to the cashier's to have it changed. [a few minutes later, the waiter returns with the new bill.]
[speaker001:] I'm sorry for the miscalculation. Here's the new bill. Would you mind checking it again?
[speaker002:] That's all right.
[speaker001:] If you're staying at our hotel, you may sign the bill.
