Exactly as Dice said. Working at Gamestop gives you shit hours anyway (I get about 4-8 hrs a week) and if your numbers go down, you're screwed. And the way corporate counts numbers is retarded.
Say I have 20 customers in a day. 10 of them have our paid rewards card and 10 of them have no card. Corporate *only* looks at how you did convincing the 10 who didn't have cards to get one. Better yet, if I convinced 5 of those 10 customers to get paid reward cards, I would still be seen as having low numbers because I didn't convince any of the remaining 5 to at least get our free card. Paid cards don't count towards your free card numbers. They don't count *against* them, but yeah... so retarded.
So once a store is in a location long enough their numbers start to look like shit because they've already convinced everyone they're going to convince to get a card. And don't get me started on trying to maintain pre-order numbers after a huge release season ends.
Anyway, sorry for the rant but it was a bit therapeutic.
