Let me take care of the check today 今天我来买单
going Dutch AA制
pick up the tab 替人付帐
Brad：Let me take care of the check today。
Lucy：Why? It’s unfair. How about going Dutch?
Brad：You paid last time because I didn’t have any money, remember?
Lucy：Oh, come on. I almost forgot. Don’t worry about it. I didn’t mind picking up the tab last time。
Brad：But you really should let me treat one time. I’d feel like I owe you one if I didn’t。
Lucy：OK. But it’s only for this time。
Brad：What’s the damage?
Lucy：It’s 12 dollars and 80 cents altogether. But don’t forget the tip. It’s usually 15%。
Brad：(to the waiter) Check, please.
