Y: Waiter!

Y:服务员!

X: I'll be with you in a second. Uh...Yes, ma'am?

X:我待会儿就过来。噢……女士，你有什么事呢?

Y: This is not what I asked for, I'm afraid.

Y:这东西恐怕不是我所要的。

X: Oh, I'm so sorry. May I ask what you ordered again?

X:哦，真抱歉。容我再问一次你点了什么好吗?

Y: Yes. What I ordered is roast beef, not roast beef sandwiches.

Y:好的，我点的是烤牛肉，而不是烤牛肉三明治。
