"No I don't have to 'do better than that!' 

I am growing weary of your cheap negotiating tactics...and your failure to appreciate all that I'm trying to do to assist you in your career.

I think I will simply deal with one of the other applicants who interviewed for this position.  Perhaps that person will prove to be more reasonable.

Our meeting is now at an end.  It is unfortunate that we could not agree on terms.  I wish you well in your job search.

Critique:

Obviously, this negotiation session was not successful.  You may wish to reflect on why you did not reach an agreement.  Feel free to play again to try to secure an agreement.
