this might be a good way to keep from getting door dinged

I parked in the nearest open spot (on the right of the photo) and then realized that if I left the cart be, and not return it to the corral, it would keep that side of my car from getting door dinged.

Then it occurred to me that maybe, that cart was put there so the other car wouldn't get door dinged. I wonder if that other car put it there, or if anyone has gotten to realize that the best way to keep from getting door dinged at the grocery store is to pull a couple carts alongside their car
