Hundreds of pumps. It's a goddamned ocean of concrete and steel. You can use the main building as a shelter for a mid-sized town and have enough bathrooms. It's a fucking department store serving as a gas station.
Yeah, sadly, it seems no matter how ample the parking, people will still just take a pump.
I kinda get it, but at this point, we should all know better. Leave one person behind to pump and park, you're going to be in the building for awhile just trying to get snacks and get checked out. I've never seen our local less than packed inside.
