It depends on the context. Did he make the comment in a positive tone or was it obviously negative? With Wal-Mart, it seems people either love it or hate it. If it was negative, perhaps it had nothing to do with how SW treats their employees. It might simply be that he was comparing SW's low fares to WM's "always low prices" attracting a certain demographic with their clientèle. I don't know....just playing devil's advocate.
