Broem, WMs are designed and laid out in such a way that you have to do a lot of dodging and weaving on purpose. They put those little kiosk island obstructions in the middle of the aisles so when you get behind Big Bertha and her fourteen children orbiting her fat buggy, you'll end up going down another aisle in frustration, and they hope you'll see something else in that aisle that you want. It's an intentional obstacle whose purpose is not so much as a "key item" but an ergonomic consumer diversion.
The aisles at WM are also intentionally smaller (in width) for this very reason too. If you're trying to get down an aisle, and Big Ed's Ass Farm is standing in the middle admiring the Hot Wheels, you can either squeeze by (doubtful) or turn around, go up the next aisle, and come back down the other side. WM is banking on you doing the latter, and they hope when you go down that second aisle, you'll make another impulse purchase.
There is a rumor that WMs are also designed in such a way that the stock shelves can be easily moved to the side and the store floor can be used for an emergency medical center in the event of a terrorist/nuclear attack, but I have yet to see any real confirmation of this one way or another.
Regarding censorship. Why does Walmart not sell CD's with harsh lyrics but they sell Rated R DVD's and MA Videogames that have worse language plus all kinds of sex on top of that.
WM is fairly inconsistent with this type of thing, so I have no idea. I find the fact that record labels and/or "artists" such as that paragon of freedom Fred Durst
and others allow the edited versions to be made more offensive than someone saying "****." If WM had its way, I'm sure that movies would be edited down with all the "dirty stuff" (which you'll notice always involves sex and rarely violence) taken out, and they are actually one of the key investors in this really dubious DVD technology created by a "Concerned Parents Group" (which is, as usual, a group of people who have nothing better to do with their time than tell others what they can and can't do under the guise of "Think of the children!") that is programmed to automatically fast-forward through/remove all the offensive parts. Hollywood studios are standing up to combat this company, so WM might not get its way after all.
WM has apparently instituted a policy that they will no longer carry any video game rated MA and that they will require any person who purchases an R rated movie to produce identification first. Whether this will succeed, I have no idea, but remember kids, it's wrong to listen to Snoop Dogg talking about popping caps in people's asses, but check out our new stock of hunting rifles in aisle 12!
I've been keeping an eye on WM for well over 10 years and I know a lot of little tricks they pull, so if anyone has any questions, post away and I'll ramble on for some more.
