There are exceptions to every "rule".... well, most rules. I've managed retail most of my work life and I'm regularly amazed how some newly hired employees will excel in performing their duties while others of whom I had tremendous expectations performed terribly. I'm not naïve enough to believe that how someone acts in an employment interview is going to be how they act on the job but the difference sometimes can be utterly astounding. We use secret shoppers to evaluate their retail performance and I've had cases where I just could not believe the secret shopper report was of the same person I interviewed and hired.
If a Gamestop employee is ignorant of a $5 discount promotion of THIS sort, that's a corporate and management failure. If a Gamestop employee is ignorant of PC gaming when they're hired, well although it's amazing that someone with an interest in electronic games could be SO clueless, again I'd say that's a corporate and management failure not to provide the necessary training. But my biggest gripe about the EMPLOYEES at Gamestop is that a lot of them don't seem to give a shit. I suspect they get ZERO commissions. Because most of them make NO effort to find what you're looking for, OR to see if an item can be "special ordered."
Of course, it's even worse at Walmart! That's why I'd sooner get 4 wisdom teeth removed without anesthetic than to shop at Walmart altho when Sony has a triple-SC promotion I don't have a choice other than to try to go "off times" so I don't get run down by women with loaded carts trying to keep track of their 5 or 6 juveniles...
