ya, I agree with Mud. You should be able to get the money out of him somehow.
You're definatly handling this all very well though. I don't think the guy would be doing so well these days if he had done it to me.
With my Chevy ('74 on 44's....and it's loud and ugly), so many kids try to either "show off" when the're drving next to me on streets, or get pissed off for some unknown reason (just jealous I guess) and act like they want to fight me. I usually just staire at them and they calm down REAL fast. If not, I get out and then they run away.
I've even had so many adults get out and try to start a fight. They think that they're real tough just because they're older than me...which makes it really hard not to just laugh at them!! In those cases....it's usually just a simple "hey, you really don't want to mess with me" that calms them down real fast!
