[speaker001:] Is this a duty-free shop?
[speaker002:] Yes, sir. What can I do for you?
[speaker001:] I want to buy some specialties. Can you recommend me some?
[speaker002:] Sure. I strongly advise you to buy a bottle of perfume and a lighter.
[speaker001:] Fine. They look nice. I will take both of them.
[speaker002:] May I have a look at your passport, please?
