M: Good morning, can I help you?
W: How much does this microwave oven cost?
M: ＄280.
W: Can you give a discount for it?
M: Sorry, I can't. The price is fixed.
W: Come on. Cut down the price just a little bit. I can buy it in another store, but I choose to buy it here as your store is nearer to my place.
M: Well, because I have to meet a quota in order to get my commission. OK. I'll take off, let say, fifty dollars. How does that sound?
W: Oh, no. I was thinking maybe more in three digits. Something like one hundred?
M: Please. That' s too much. Seventy-five, no more no less.
W: Give it two zeros like a hundred. I feel luckier with zeros.
M: Alright, eighty is the bottom line, we can't make any profit if the price is lower than $200.
W: OK, I'll take it. Be sure to have it securely packaged.
