[speaker001:] Can I help you?
[speaker002:] I want to buy a hat.
[speaker001:] Come here, please.
[speaker002:] Is this one fit for you? It is nice.
[speaker001:] I don't like the style.
[speaker002:] How about this one?
[speaker001:] Black is not my favorite colour.
[speaker002:] You must like this pink one, don't you?
[speaker001:] It's pretty. How much is it?
[speaker002:] Fifty yuan.
[speaker001:] It's too expensive. Can you come down a little?
[speaker002:] How about forty-five?
[speaker001:] I'll buy it if forty.
[speaker002:] OK.
