Here's your tip.

This is your tip.

Keep the change.

I tipped the waiter $5.

I gave the waiter $5 as a tip.

A: I'd like to settle my Bill, please. 

我要买单。

B: Your bill comes to $52, plus a ten percent service fee. The total is $57.20

您的账单为52美元外加10%的服务费，总共是57.2美元。

A: 

That doesn't sound right.

Can I check the Bill, please?

听起来不太对劲，让我核对一下帐单好吗？

B: Certainly, sir. Here you are.

先生，当然可以，给您。

A: Oh, I see what the problem is. You have charged me for two bottles of wine. We only had one. 

哦，我看出问题所在了。

你收了我两瓶葡萄酒的费用，我们只喝了一瓶。

B: I'm sorry. In that case, the total is $44. Will that be cash or charge?

对不起，如果是那样的话，总共是44美元，请问现金还是刷卡？

A: I'll pay cash. Just a moment...I can't believe it; I don't have any cash on me. Never mind, here's my Visa card. 

我要付现金。

等一下，我不敢相信，我身上没带现金。

没关系，这是我的Visa卡。

B: Thank you...I'm sorry, sir. Your Visa card has a problem.

谢谢您。

先生，不好意思，您的Visa卡有问题。

A: Oh, no! Don't tell me it's expired.

不，别告诉我它已经过期了。

B: I'm afraid it has indeed expired. 

恐怕它真的过期了。
