"What?!?!?  After all I'm offering you, you want me to ALSO pay for books an professional memberships?  What next?  Babysitting for your dog?  Free car washes?  I'm sorry, but I don't think I can do business with someone who is so greedy and grasping as you...

Have you ever heard the phrase 'the straw that broke the camel's back?'  Well you have just loaded on 'one straw too many!'

Our negotiation is at an end.  I think we will pursue other prospects and I wish you well with your job search."

Critique:

Obviously, you did not reach an agreement.  Do you know why?  Perhaps you might want to play again...
