going Dutch AA制
pick up the tab 替人付帳
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.
