Sorry, but the gamestop clerk didn't really like you.
See, they find marks, act really nice to them, ask to hang out and stuff. Then you invite them over and they're very polite. A few weeks later, it'll seem like the gamestop employee is your friend or possibly even your lover. But eventually, you will put it together that he's gotten all of your friends and relatives, individually, to pre-order a game with him.
