I parked my car round the corner from Newtown Sauna in Edinburgh, bought a ticket for pay & display, but when I came back a couple of hours later someone had crashed into my drivers side door!!!
I was convinced it would've been reported to the polis and worried for hours, had to drive home with the door not fully shut as the door pillar was damaged. But luckily it was a hit and run and I managed to sneak it in to a body repair shop 2 days later, paying for it from my punting fund.
I'm always careful with speed limits, parking, etc when I'm somewhere I shouldn't be, but there's no way to avoid random stuff like that!
