Former employees are usually bitter, its actually a pretty decent job if you actually run your store and do it right. I'm not in the beta, Sony had it at our conference this past week for us to play. They gave us all the code for Kratos. Oh btw, if you do want more cool free codes for Kratos type Sack boys, Bio-Shock for PS3 for a limited time will include a code to get a Big Daddy Skin for Little Big Planet.
edit: I should add though that Gamestop Canada is run very differently then the US though, but I left and came back when I realized all companies are the same and it was my crappy attitude that was holding me back, not the politics.
