Title misleading
To say Apple Reps in CompUSA are "Apple employees" is misleading. These are most likely ordinary redshirts who decide to get a job pushing Apple computers (and AppleCare) for whatever reason. Very few seem to be genuine Apple enthusiasts or users of any technical prowess (if they were, they'd be certified techs not sales people).
They technically work for Apple, but so did I on several occasions during Demo Days. I was not really an Apple "employee" though, I was merely representing Apple in the CompUSA and got paid by MarketSource on Apple's behalf, kinda like a temp agency gig.
The Apple Reps may get some kind of training, but they may start out being total Windows/Linux PC bigots. Garbage in, garbage out.
And yes I did "sell" some Macs. Of course not working for CompUSA I had to hand off the sales to a redshirt, who were literally grappling each other for the credit (and SPIFs). I witnessed firsthand the "hard sell" of CompUSA warranties, more points for the redshirt.
I even had one redshirt come over from the Windows side and tell a potential Mac computer buyer that "MACS" are bad because they can't run Linux, and the redshirt helpfully told the clueless consumer which distro he ran at home as if the customer even knew what Linux was. BRAVO!
I quickly changed the focus of the conversation and made a new Mac user. Morons. Apparently simply reading Slashdot or managing to install Redhat on a PeeCee does not actually make you any smarter, based on my personal experience.
If you get a bad Apple Rep, politely correct them or just smile and nod approvingly and get your stuff and get out. Maybe they will learn, but more likely they will quit and go work at Circuit City or BestBuy where there are no eeeeeevil MAC computers that can't run Linux or do any real work.
