That might be me putting a shopping cart in your parking space.
I deliberately park at the far end of the parking lot and I've still had many of my vehicles dinged and dented by inconsiderate shoppers opening their car doors into mine. Now, when I park I locate a loose shopping cart and place it in the parking spot next to mine to prevent idiots from parking there and damaging my car.
I still park at the far end of the lot away from all other vehicles, so if someone is still parking right next to me, it's because they're an A-hole.
