Gosh, that must have been a sucky encounter... I had somewhat of a similar encounter back in Aus when I collected my R53 JCW MCS of which was 36hrs old.
My gf and I parked at the cinema car-park and some cracked up guy hassled my gf and I for money. I felt sorry for the guy and gave him $10 to leave us alone BUT unfortunately he felt that it wasn't enough and pestered me for more but i didn't give in. The prick decided to snap off my fogs of which infuriated me beyond self-control
so in turned broke broke his arm and cracked his jaw nicely. Felt good at the time BUT it sucked when I was slapped by a cop for grievous bodily harm and fined $1,500 despite the fact I had three standing witnesses.
The thing I didn't get to this day was given the security in the area, WTF didn't they do anything to keep the crack heads away from the premise or even break the fight up if it was foreseeable.
Was the most expensive movie ever to date.
