I'm a poor graduate student. WalMart fits my budget. That's the only reason I shop here.
Depending on where you are in the country, you might actually stumble into a WalMart that doesn't make you cringe. Unfortunately, this isn't one of them. WalMart's clientele is what I would call "special." You'll come across many interesting people wandering through the aisles here. I'm surprised more haven't shown up on peopleofwalmart.com.
It may be hard to believe, but I have experienced worse WalMarts before. But if you can afford to shop elsewhere, you'd be better off.
