A: Will you have a cup of coffee, Mr. Wang?
B: No. Don't bother, please.
A: Of course, i don't know Smith at all, but you've got to be on your guard against George. I told you about our negotiating with him in New York three years ago, didn't I?
B: I am sure you did. Can we focus on the final packing today, Mr. Brown? We mustn't get stuck in the price. They are going to knock us down. We have got some room to maneuver.
A: That's right, George is the head of Marketing Department.
B: What we must keep in mind is that we can make a concession if they push us on staff cut.
A: Oh we don't need to worry about that, Mr. Wang. We will just play it by ear.
