Interestingly this is very different from my perception of the games retail industry in the UK. I've known a few people who've worked in Game and Gamestation shops, and all of them have been keen gamers. A friend working for Game also told me about how employees were encouraged to take the new releases home, for free, to play through so they knew what they were talking about to customers. For those who didn't own a particular console, (despite the decent hardware discounts) each of the current generation static and portable machines were there in the staff rooms to be used on breaks. Finally, I don't think I've ever encountered an employee in one of these stores who wasn't able, and willing, to engage in a reasonable conversation on games. Very often they'll express an opinion, be it 'Buy Arkham Asylum now' or 'Yeah I'm not surprised you're trading Haze in'. It would quickly become apparent to me if someone had played nothing but Madden and Dead or Alive.
As for the whole 'gutting' thing, I can't see what the hell people's problem is. It's not like there isn't a very, very good reason for it. Thieves are arseholes, anything that prevents theft is a good thing. In the long run, prevention of theft keeps costs down for all of us. And what, you think those disks were born inside the box? Of course it's still a new game, long as it hasn't been played/scratched/pissed on by anyone! Long as it works, no issue.
Edit: Oh, I guess the whole 'gutting' thing is pretty dull for the employee, but what are you expecting when you take a low grade position in high street retail? It's really no different from stacking shelves. The narrator even starts out saying he wanted something low-pressure, low-effort, low-responsibility. I'm not being snobby, these are the jobs most of us start out in and build up from. Hell, I wish mine had been in a games shop rather than a burger bar!
