Three parking tickets, totalling £90 (I think). Two of them were when I was parked outside my own house without a permit. The traffic warden put them on the offside window facing the road so I wouldn't see them, and put the second one over the first. I nearly put a brick through the town hall window for that piece of sheer, unnecessary nastiness.
A couple of years later my housemate was in the same situation, and got let off when he moaned. Wish I'd done that.
Oh, and the third time, I went back to put some more change in the car park machine, only to find I'd already been ticketed. On my way back down the parking attendant got in the lift and greeted me with a cheery smile. Technically I was at fault so I resisted the urge to nut him.
