Wal-Mart, uniquely among large stores I've been in, makes me feel bad. I don't remember this being the case, say, 20 years ago. It seems to have worse over time. I think it's the lighting and design, though I'm not sure exactly what about it. Walking in instantly makes me miserable. Probably doesn't help that shoppers and workers alike all look sad, constantly (but how much of that is because the store itself is doing that to them?)

Also, nobody in them seem to know how to exist in public without constantly being in the way. Wal-Mart has an uncanny ability to feel crowded while not actually being crowded. I don't get it.
