A: Could I have my bill, please?
B: Certainly, sir.
A: I'm afraid there has been a mistake.
B: I'm sorry, sir. What seems to be the trouble?
A: I believe you have charged me twice for the same thing. Look, the figure of 6.5 dollar appears here, then again here.
B: I'll just go and check it for you, sir.

A: 请给我账单，好吗？
B: 好的，先生。
A: 恐怕这里出错了。
B: 对不起，先生。请问有什么问题？
A: 我想你们对同一种东西进行了两次收费。看，6.5美元这个数字出现在这里，然后这里又出现了一次。
B: 我这就去为您核对一下，先生。
