When shopping you should always try to park as close to the main entrance as possible because there's more pedestrian traffic. Not perfect but still the best idea. I was parked at the upper end of the lot so very few people walking by.
In today's World getting "involved" means recording things on your smartphone to post online. If the roles were reversed these same people would be screaming for help. Karma doesn't take sides in ones life.
I park as far out as I can to avoid door dings. I never park next to anyone.
When Walmart was open 24 hours, I'd go around 2AM. I've found in my location the best time to go is around 7PM Monday thru Thursday.
