It might just have to do with the fact that some people actually find it helpful to be able to shop then. I don't believe that Wal Mart is being "greedy" because if it wasn't cost-effective to stay open, they wouldn't!!!! I have a friend who works the night shift at a Wal Mart - she actually asked for that shift - it fits into her lifestyle - imagine that!
But that wouldn't be allowed in the "world according to Aliska". boy, what a wonderful world that would be. LOL!!!!!
