CAROL: I never understand why these shops have so much liquor. JOHN: What do you mean? It's because it's much cheaper to buy liquor duty-free. CAROL: But why? Why don't people like to buy shirts duty-free? Or shoes?I just don't understand why it's always liquor. JOHN: Well, it's because in most countries liquor has a higher tax on it. CAROL: You mean liquor has a higher tax than other things? JOHN: Yes, of course. Didn't you know that? CAROL: No, I didn't. How high is the tax? JOHN: Well, it is different in different countries.But it's because of the high tax that buying liquor duty-free is such a good deal. CAROL: Why would the government want to tax liquor so much? JOHN: Liquor is considered a luxury item.And also, it is considered as something that isn't very healthy.So if people want to buy it, the government thinks it has the right to tax it. CAROL: That's why a lot of people buy cigarettes here too, isn't it? JOHN: Of course. Cigarettes are also taxed very heavily. CAROL: Now I understand. But I don't smoke or drink.So what am I supposed to buy in here? JOHN: You can buy some of these nice butterflies. CAROL: No, I'm sorry.I don't think it is nice to have butterflies mounted in boxes.It is kind of disgusting. JOHN: What? You feel sorry for the butterflies? CAROL: Yes. I think they should just let them fly free,and not try to sell them to foreigners. It is a kind of destruction of nature. JOHN: Well, I agree with you.I'd rather think that the butterflies are flying around in the mountains.I just wonder if they really catch so many that it affects the butterfly population. CAROL: Who knows? Hey, I like these jade bears here. JOHN: How much are they? CAROL: This one is 2300 dollars.Maybe I should buy it for my mother. What do you think? JOHN: If you want. Didn't you buy her a small vase already? CAROL: Yes, but she would like this a lot. She likes to collect little things like this. JOHN: Alright. Buy it then.I won't buy anything. Well, maybe I'll buy some Cognac. CAROL: Maybe I could buy some Cognac for my brother. He always drinks it. JOHN: Let's go ask about it.
