I seem to get frustrated/angered with almost every trip to Wal-Mart, mainly for the reasons many of you have already mentioned:
*Waiting behind someone slow/looking in the aisles.
*The parking lot and all associated problems.
*The general disarray of their store(s)
Overall, I guess most of my problems deal more with the people shopping there (and the number of them, our local WM is always jam packed) and not as much with the clientele. We've had some issues in that area too, but overall it is waiting behind someone (sorry, but usually old and/or overweight...and/or with several kids) who is gawking at one of the "deals" or "featured items" in the middle aisle stack or endcaps. The stacking of product in the aisles is really frustrating and makes it near impossible to get through their stores. However, all those complaints aside, we do end up shopping there for our groceries, etc. They are just the cheapest, and have about everything. However, if a "Super" Target (we only have "regular" ones here in town) were to open up close by, I think we'd pay the little bit extra and shop there. Speaking of prices, I've found that Wal-Mart doesn't seem to have the "lowest price" nearly as much as they used to...specifically on DVDs. The last couple of months I have gone looking for new DVDs/boxsets, and if I hit Target the week of their release, their special sale is usually significantly cheaper (often $5-10 or more). Needless to say, the bullseye has been getting much more of my DVD business. In our case, WM is close by so it becomes more convenient overall. However, like I said, I almost always leave that store in a terrible mood.
