A：Miss. This is the blazer I've been looking for. It goes well with my brown pants. But there is a button missing.
B：There are several others on the rack. Why don't you go and search for a good one?
A：I did. But they are not my size. Too big for me.
B：Well, let's put it this way. I'll take 10% off the sticker price for the missing button. You can try to get the button somewhere else. OK?
A：10%? Sounds reasonable. I'll take it.
