X: May I help you?
Y: Yes, I'd like to see that pen.
X: Oh, that's really a good buy. ...Here. There's only one left.
Y: Can I get it duty-free?
X: Sure, if you show me your passport.
Y: It's not the latest model, is it?
X: No, it isn't. That's why it's such a bargain.
X:要我帮忙吗?
Y:是的,我想看那枝钢笔。
X:哦,这枝笔很便宜。……喏,就剩下这枝了。
Y:我可以免税买下它吗?
X:当然可以,只要你把护照给我看一下就行了。
Y:这不是最新的款式,是吗?
X:不是。所以才会这么便宜啊。
