Negotiating with an S.O.B.

Along these lines, you'll find some advice on how to approach a tough negotiator, whom I'll refer to as the S.O.B. This negotiator is abrasive, difficult, abusive, unjust, rude, illogical, disrespectful, challenging, and self-centered. He is ruthless in his pursuit of his goals and has no hesitation about causing you or others inconveniences. He arouses vexing emotions in you, infringes on your rights, and makes you feel helpless. It would be better if you could use ethical and clever ways to mitigate the negative effects that the S.O.B. has on you.
