Nastiest Walmart Supercenter I ever shopped in was in Irving, Texas. I was the only white face in the store, including the employees. Mostly brown, with some black.
The one I usually shop in is much nicer, even though it is largely Mexican and Asian, with a sprinkle of salt and pepper. There’s another Supercenter for whites about 3 miles down the street for whites. It’s really nice.
My experience would support the conclusions of the article that whites keep their stores nicer than do folks of darker skin tones.
Having worked in a discount store in a tough area some of the factors I had noticed:
1) Shelves torn up to a much greater degree due to the high incidence of shoplifting.
2) Children not supervised who run around knocking things open, spilling, tearing open packages, etc.
3) Lazy, unmotivated help that does not go out and return the shelves to some semblance of order.
4) Homeless and junkies wandering into the store to get warm, leaving messes all about, some of which should not be mentioned here.
5) Overnight crews to put the store back in order cannot be scheduled as everyone is afraid to be there between the hours of 10PM-6AM.
