Excellent link...good read.
I've never critized Wal Mart for any of their business practices, I just always find it amusing what I encounter within the stores. They all seem to be a parallel universe, with people that I neither see or encounter anywhere else. It's kinda freaky!
I live close to a Wally Super Center and I spend far more money there than I wish I did. There are other grocery stores within a couple of miles, but they just don't have the selection and price. You literally feel like your are throwing your money away to pay 30% more for something than you could have got it at Wally.
The customers are the real circus. You just wonder where in hell did they come from? You see more bizarre individuals and behavior at Wally than any where else. Wally would be an excellent place for someone doing some kind of graduate sociological study of various aberrant behaviors!
Now sometimes I'll go to another store just not to have to fight the crowds at Wally World, but I always feel guilty.
Wally is here to stay, they are definitely doing something right and they fit a very big niche in our retail world.
