I have a related story about job offers. I had a job offer fresh out of University, for about half of what the standard salary was at the time.

After some thinking (2min... NO), and letting them stew for a few days, I told them "No". They asked if it was because of the salary. "Yes, yes, it is". They immediately doubled their offer.

Sorry, but the answer is still "No." If the first contact you have with me is that you try to screw me and assume I'm stupid, I will not work for you. I'd be better off unemployed.

I found another job 2 weeks later, for more than their second offer. And those people didn't play games.
