I just don't care for Walmart because the one near me is always very dirty. There are stains on the clothes hanging up in there, there is a layer of dust over the produce, and a team of scientists with strong stomachs might be able to determine what exactly that stuff stuck to the floor is, but I can't. This is, of course, the fault of my local Walmart management and staff, and whoever's supposed to keep them on the ball. And when they built the place, they really messed up the traffic in the area. It takes real effort to actually make it to the Walmart here.
The Walmart I went to when I lived in Macon, however, was actually quite nice, much cleaner and more organized than the Kmart across the street. The one in my parents' town is middle of the road: a bit messy, but not dirty.
My point is, not all Walmarts are the same, any more than all individual restaurants in a chain are the same. Haven't you all experienced The Bad McDonald's? You know, there's always one McDonald's in town that's so much worse than the others, and everyone knows it and calls it The Bad McDonald's. "I got chicken nuggets for lunch." "You didn't go to The Bad McDonald's, did you?" "No, I drove past it and went to the one by the mall."
