Sales person: May I be of any assistance?
Shirley: I want to have a look at the microwave ovens.
Sales person: You can have a broad choice here. Are you interested in a particular brand?
Shirley: Not really. What are these toys over there?
Sales person: Ma'am, these are complimentary with each purchase. How about that one below the toys? This is the best seller. They are of the latest model that can be found in town.
Shirley: I don't like its color. A bit too bright. Do you have a grey one?
Sales person: Yes, we do. What a great taste you have! But we only have one left in stock.
Shirley: Really? How so?
Sales person: You know a good product will always sell! Would you mind waiting for a while, we'll get it right away.
Shirley: Okay.
(The salesperson brings a beautiful grey microwave oven.)
Sales person: Here it is. It's very elegant, I think you will like it.
Shirley: How about its quality?
Sales person: Its durability will be a big surprise to you.
Shirley: What about the price?
Sales person: 500 yuan. And if you buy it today, there will be a 15% discount for you.
