I have a deep-ridden hatred towards my local GameStop. Mainly their advertising of buying any used games. When it just opened, I notice the advertisement about buying games for cash, believe it or not there aren't that many stores around here that do that, and of course went there with a backpack full of games I wanted to get rid of. Games I had played through several times but were in great condition, games I had first bought individually and later gotten in some sort of collection, games I had lost interest in after a few hours of gameplay and so on. So, I get there and get ready to sell my PC games, just to learn that they won't accept them, because of some mumbo-jumbo about not being able to guarantee the condition of the games. I say pfah! Screw them and their silly store.
Although, I have frequented it at later dates due to their excellent collection of "three for the price of two" games. Cheap, great games. Awesome. I still hate 'em though. Damn snobbish douches... -shakes fist-
Another thing I hate is when people offer cheap Nike shoes but won't live up to the promise of said free shoes. I want my cheap Nike shoes, dammit!
