Man this is spot on. 8-12 years ago it wasn't like this. In my hometown most of the people that worked at EB which now is turned into Gamestop, were genuinely pretty cool. I live in a college town now, and these new guys can be dicks.
One day I went in to look at the XBox 360 wall and decided to pick out Army of Two when it first came out. I went to the counter and asked for Army of Two, hesitated for a second and said, "for the 360". The guy next to the person I asked that also worked there said in a sarcastic voice, "Well, yeah, I saw that you were looking at 360 games." I just gave him the Rambo thousand yard stare for 5 seconds and said "Yes, the 360!". He got a little nervous as the other guy rang it up. This guy looked like the geeky kid with bad breath and shit his pants in high school. What the hell kind of confidence can he possibly have?!?! I wanted to say, I bet I know a lot more about games than you ever have you cock-smoker, so don't talk to me like I'm a dumbass.... but that wouldn't really sound right, lol. I guess he thought I was like most customers that don't know too much about games and dared to put me in that category. He didn't expect me to look at him with such intimidation.
I'm a bartender man, you gotta show no signs of weakness when people pull that shit. I would have people threaten me, be smart asses, act dumb to get out of paying tabs, you name it. The best thing to do is not apologize if you did nothing wrong and 1-up them in a cleaver, yet humble way.
Anyway, I think most of those guys are gone at that store and now I see decent people that work there.
