May I help you?
Yes, I would like to buy a swimming suit for my older sister as a birthday present.
What size does she wear?
Medium, the same size as I do.
Would she like this style?
No, do you have something different from this one?
What about that one?
The style is fine, but the color is too dark. Do you have something brighter?
How about this one? It's too expensive. Do you have something cheaper?
Yes, we do. There is a budget department on the first floor. Why don't you check there?
