Good morning, sir. Can I help you?
I'd like to buy a blue jacket. Do you have any blue jackets?
Yes. What size do you wear?
I want Size M.
Here you are. Try it on and see whether it is all right for you.
It's all right. I like it very much. How much is it?
360 Yuan.
Oh. That's a bit expensive. Do you have any other kind? I want a cheaper one.
What about this one? It's only 120 Yuan.
OK. I'll take this one. Here is the money.
