I remember once parking over 2 spaces in our local Sainsburys, couldnt find a parent and child and had a huge car seat to try and get out. There were loads of spaces so I wasn't stopping anyone else parking.
Came back to see the following note on my windscreen written on a KFC tissue.
(Sic)
"grate parkin u nob."
Well, I thought to myself, I might not be able to park but I am at least literate.
