Three things really stood out as negatives.
The hours sucked, you'd have to work till midnight or get there at 7 depending on what shifts you get.
The management wasn't too great, though I don't really hold it against them because a lot of them where new at the time.
They have this really annoying point system, you get 8 points, and if you screwed something up, then you'd lose a point, when you hit the eighth one, you get fired.
