It's one thing to park inconsiderately at a large car park, where there are plenty of spaces, and people can usually find somewhere else to park if someone has blocked off two or more spaces by leaving their car somewhere stupid. Outside a small store, where parking spaces are limited, it's a much larger inconvenience. There might be no other spaces available, meaning shoppers are left having to haul their shopping further down the road.
There's no way the situation we see here occurred without the support or assistance of the store which owns all of those shopping carts, so we presume that this is an example of a business taking revenge on behalf of its customers. That's a circle of steel, all connected together. We're not sure how you get out of this, to be honest. The answer probably lies in going into the store, admitting you're the terrible driver, and pleading for mercy.
