had a similar thing with a car before...
mate parked with the front of the bumper overhanging a residents space (he was on a yellow line, but it was out of hours)
there were no other cars down the entire road, not blocking anyone etc this is at about 11pm
went to equinox n stumbled out at 3am to find a fookin clamp on the car that was put there at 2:45am!
i mean, WHY! clamping someone whos not hurting anyone and just happed to be about 2inches over their space due to crp parking... at 3am in the fookin morning with NOBODY else about?!?!?
thing is we needed to get home so he HAD to pay to get the thing removed (after a 1hr wait)
