Summary: Pretending to be on a counterpart’s side while consulting another party who keeps vetoing deal points.
The Good Guy/Bad Guy technique is very similar to the tactic of the Higher Authority but is much more specific. With Good Guy/Bad Guy, one person pretends to be on your side and appears to help you make the deal. But every time you strike a deal, the good guy marches off to the bad guy for final approval. Naturally the bad guy will renegotiate the deal you have worked out with the good guy. Anytime you get into this scenario and do not expose the technique, you can end up with devastating consequences.
Example
If you have ever bought a new car, most likely you have experienced the frustration of being in a Good Guy/Bad Guy situation. After you have test-driven the car, the salesperson takes you into the closing room to draw up the initial deal. Since the salesperson cannot approve anything himself, he marches off to the sales manager to get the manager’s input on the deal. Then the salesperson returns and says that you are close, but the original deal will not work. What is scary is that dealerships go through this process whether your offer is a good one or a bad one.
