word. Someone very close to me is a nine-figure guy, ($100M+) and absolutely HAMMERS people on everything he buys. He bought a car a while back, and he hammered the dealer for like 3 hours. I think he saved $4,000. He wanted a rental house out of town and hammered the owner of the house for an hour to save $750/month.
I asked him about it - I said, "In the time you spent meating up the dealer, you made enough money to buy 5 cars. Why did you hammer him so bad?"
And he said "I guess I have always been that way". It was just second nature to him.
There is a lesson there...and no, he is not hammering these peons to amuse himself.
