It doesn't matter how much you patronize the store - they will have your car towed anyway - all in the name of everyones safety - because having your car parked there doing nothing at all is a grave imposition on everyones safety.
If however you are a teenage kid with a skateboard - you can practice your skills all you want in the empty parking lot at any hour of the night despite the clearly posted signs not to -because Target is so very concerned about your safety and that of your children.
Oh yes, you can send your kids to Target parking lot with their skateboards and make sure they are dressed in dark clothes so that no one can see them - that increases their risk of getting hit by a car because Target is so concerned about everyones safety.
Or maybe they just let the skateboarding kids roam free in their parking lot every night because they know they are going to tow all the cars anyway and that of course eliminates the possibility of the skateboarders getting hit.
A little bit of a convoluted approach towards safety concerns - don't you think ?
