I heard a story about a friend of mine in San Francisco. A car almost crashed into him by turning into his bike. Of course it was the car's fault. And then out of this car comes a pissed-off guy. A HUGE pissed-off guy.
Well my friend is worried that he's about his ass kicked by an asshole driver. But he's also pissed off, too.
So my friend puts his bike helmet on the ground, takes out his wallet, and throws 5 crisp $20 bills in his helmet. He looks the guy in the eyes and exclaims, "I don't fight for free!"
The asshole gets back in his car and drives away.
