you're right, they're not all that way.
but you have to wonder how low the odds are that you would find one that ISN'T that way.
I live within 3 miles of 2 different Walmarts.
while I don't see this kind of thing EVERY time I go there, I see it often enough. and one of the two walmarts within 3 miiles of me is worse than the other. one of them I wouldn't go there at night without an armed escort.
