I’ve seen these parking spots at every Walmart I’ve been to recently in multiple states (I go camping a lot and they’re very useful if I need any food or supplies or if I need to replace a piece of gear). It seems like corporate just made a decision to put them at every location. I have yet to see police park anywhere except the fire lane though, I once saw fifteen cop cars parked in front of my local Walmart in the fire lane, it was just they were all buying Christmas gifts to donate I found out later.
