Had a similar experience with a Beef-neck. I was driving onto a dual carriageway, my friend was in front in his Golf and did a dodgy overtake of the megane in front (mates a bit silly), anyway, i get onto the dual carriageway and overtake the megane normally as does another friend in his 205 behind me and we turn off at the next slip road. I follow my friend in his golf and we turn into a car park, not only to have the megane that my friend dodgily overtook follow us. I clocked him and didnt park up as he looked like he was going for my friend, and my friend drove away as well! anyway, im driving around the car park, about to leave and this beef neck tries to catch my friend, and is unsuccesful, so he walks towards my car! aarrgh i think, and hes walking right in front of my car, so i stop and know i havent done anything wrong and he says " your mate just overtook us and my woife was scared" and i was like, "well why dont you tell him?", then hes like "you boy racers, all the same" so i say "well, i gave you loads of space when i overtook safely, if anything your wife was driving too slow for the dual carriageway" and he goes "f*** off!" (in a yeah right kinda way) so i say "ok then!" and boot it and he shouts "oi!" hahaha, eat my gravel you meat head. Try and catch me in your megane boat..... Bit silly really, but he was being very threatening and was a large dude, he tryed to grab my car and slapped the rear window as i floored it away. True idiot.
