LPT: If you park in a tight space and worry you might get scratched by the cars around yours, take a photo of the situation and their licence plates just in case.

I parked next to a white van once, not too close but still while I left my car there I thought to myself- if this guy has any trouble getting out of his space, he might get my car. I also thought I was just being paranoid so I left it there. Later I came back to a huge scratch line and some white color residues. Wish I knew his licence plates...
