M: Can we make you an offer? We would like to run the campaign for four extra weeks.
W: Well, can we summarize the problem from our point of view? First of all, the campaign was late. It missed two important trade fairs. The ads also did not appear in two key magazines. As a result, the campaign failed. Do you accept that summary of what happened?
M: Well, the delay wasn’t entirely our fault. You did in fact make late changes to the specifications of the advertisements.
W: Hmm… actually, you were late with the initial proposals, so we had very little time, and in fact, we only asked for small changes.
M: Well, whatever, can we repeat our offer to run the campaign for four extra weeks?
W: That’s not really the point. The campaign missed two key trade fairs—because of this we are asking you either to repeat the campaign next year for free, or we only pay 50％ of the fee for this year.
M: Could we suggest a 20％ reduction to the fee, together with the four week’s extension to the campaign?
W: We are not happy. We lost business.
M: I think we both made mistakes. The responsibility is on both sides.
W: OK Let’s suggest a new solution: how about a 40％ cut in fee or a free repeat campaign?
M: Well, let’s take a break. We’re not getting very far. Perhaps we should think about this.
