I have only one Walmart and it is always full of people with unruly kids and a real mess with stuff thrown on the floor. A few poorly dressed people, but the PJ crowd is usually early morning. The worst thing about it is all the cons that hang out in the lot and pray on old folks, usually women by themselves. Just about every scam in the book goes on there, even in broad daylight.
The last time I was there, some guy was trying to shake me down, saying I almost ran over him. He wanted a hundred dollars and he wouldn't call the cops. I got out my cell and called the cops, reporting a con man shaking down old folks. He took off. Years ago, one of the old greeters was mugged for reporting a theft. One of the checkers had a scam going with a couple of friends.
The people they hire would be rejected by Barnham and Bailey for being too freaky. Pink and blue hair, man buns (hair), and nose rings with buggers hanging, and tattooed faces.
In times past, I have seen some young gals on the heavy side, dressed in bodycon dresses that hid nothing. I had rather see them in baggy PJ's.
