Personally, I've never seen anyone working in a Wal-Mart who appeared to like their job at all, and they certainly don't have any pride in it. That's one of the things that lend it its "terrible place to shop" ambience. Of course, you can't claim that Wal-Mart necessarily engenders that attitude, but I imagine that there's a reason that that sort of person works there. My though is that other retailers are probably interested enough in, at the least, maintaining a professional image to their customers that those employees get fired pretty readily, whereas they stay at the Wal-Mart either because Wal-Mart doesn't care or Wal-Mart doesn't get better applicants, or both.
