I met Olie Gates for about 5 minutes back in '99. We supported his accounting software and he was staring down y2k like everyone else. He carries himself strong and can be intimidating if you don't have your s**t together.
So he shows up 5 minutes late for the meeting, listens for about 5 minutes, stands up in the middle of our sales guy's sentence, and says something to the effect of:
"Gentlemen. I have $500 to spend on this. If it's going to cost me any more than that I'll buy those bitches in accounting pencils and paper. Those don't have date problems."
Then just walks off.
The best part? At the time at least one (maybe two) of "those bitches in accounting" was his daughter.
