When I lived in Superior (halfway between Denver and Boulder) there was a really nice Wal-Mart in the Flatirons mall area. It was clean, had really nice produce, was never too busy, and the customers were several steps above the quality at your average Wally. I loved shopping there, as I would save a good 30% over the Safeway next door and could get everything I needed at the same time. But every other Wal-Mart I've tried to grocery shop at has been a pain in the ass. Crazy long lines, poor food selection, and customers that make me want to punch them.
