I never understand why these shops have so much liquor.
What do you mean? It's because it's much cheaper to buy liquor duty-free.
But why? Why don't people like to buy shirts duty-free? Or shoes? I just don't understand why it's always liquor.
Well, it's because in most countries liquor has a higher tax on it.
You mean liquor has a higher tax than other things?
Yes, of course. Didn't you know that?
No, I didn't. How high is the tax?
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.
Why would the government want to tax liquor so much?
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.
That's why a lot of people buy cigarettes here too, isn't it?
Of course. Cigarettes are also taxed very heavily.
