Not me, but a good story nonetheless
I used to work as a cash office supervisor in a shitty overpriced supermarket chain. I temped a bit in a shop about half an hour from mine, because half the management had to be suspended when about three grand went missing out the safe, but whatever.

This place had a pay & display car park outside, and the attendant, can't remember the name, was allowed to use the shops break room/lockers/staff toilets/etc. He seemed like a sound enough bloke, only spoke to him a couple of times when he told all the shop staff he was going to walk out at the end of the week because he had had enough ticketing old biddies cars who didn't have the brains to remember what time they parked. (parking was farmed out to a private contractor, so no-one cared).

Friday came round, and the bloke turns up in a long-wheel base transit, One of the lifetime supermarket employees shouts "[insert attendants name here] is at it again, come look!" So me and half the staff wander over to watch the scene unfolding outside.

The transit was full of clamps and the guy was randomly clamping every car he could as fast as he could. He already had a good number done when we started watching him, and he had some guy in a suit trying to persuade him to take the clamp off his car. The attendant was eerily serene, completely failing to acknowledge that this guy even existed. Just working around the guy As he pressed on, the suit got more and more irate, and louder. After about 10 to 15 mins the suit was screaming down the attendants ear, as he carried on clamping cars. They guy just completely ignored him. I mean screaming, spittle flying, swearing and insulting this guys family, the works. By this time word had got round, and there was a crowd of onlookers watching this guy clamp cars.

Eventually the attendant gets into his own car (which apparently he left the night before and got a taxi home) and fucks off. The car park company did come out and remove all the clamps about an hour or so later, apologising profusely.

Apparently this attendant had had two previous incidents, one where he smashed the company transit (different to the one he bought with him) into the back of the shop loading bay, and one where he emptied all the machines and threw the change all over the car park. According to the shop staff he always came back after about three weeks, working for the same company, doing the same job, and they expected him back again!
