在外用餐时

● 付款

请结账。
Bill, please.
I'd like the check, please.

在哪儿付钱？
Where should I pay?

我请客。
It's on me.
It's on me. （我请客。）
Oh! How nice! （哦！那太好了，谢谢！）
This is my treat.
I'll pay for dinner.
I'll treat you.
I'll pay for drinks. （我付饮料的钱。）

我来付。
I'll take care of it.

这是什么的钱？
What is this for?
What is this charge for?
What is this amount for?

我觉得这儿算错了。
I'm afraid there is a mistake here. *I'm afraid… “我觉得是不是……”，一般用于不太好的事情。mistake 表示“错误”。

我们各付各的吧。
Let's go Dutch. *Dutch 表示“荷兰人”，而go Dutch则表示“自己的费用自己付”、“分摊”。
Let's split the bill.
Let's divide the cost.

我们分开付款。
We'd like to pay separately.
We'd like to pay separately. （我们分开付款。）
All right. （明白了。）

不用找钱了。
Keep the change.

请开张发票。
May I have a receipt, please?
