I never use a busy car park, If I cant get a space on the end of a row and on the perimeter and i usually go for the parking spot the furthest away because most others are lazy bstards and want to be near the shop doors - especially wimmins. If one isn't available I go elsewhere, however, if i really have to visit that particular business then i find a parking spot close to the car park.
Having said all of that I'm retired - so shop when i know its going to be quiet and for 95% of what i buy I use Amazon, and occasionally eBay, The only proper shopping I do is food - don't have it delivered so someone else can have all the short life products courtesy of the order pickers.
Car is three yrs old, no scratches, dinks or dents ---- so far.
I watch so many drivers just throw their door open onto the car next to them - and sometimes people are in their cars and don't react to it.
