I have yet to enter an Apple store that didn't make me hate humanity.
Every one I've been to is full of the snottiest pricks. The apple store is successful because of its excellent layout and of course the apple products, but they have a serious inability to hire intelligent people who aren't just bearded hipster tools
I've been to a few Apple interviews and they clearly state before each interview that if you don't know anything, they don't care because they will train you to do whatever you need to do the job you are hired for.
Besides, a lot of people who are smart, tend to use jargon. Apple products are so simple to use that people who aren't that tech-savvy or that don't know tech terms, can use them.
I think Apple is a good company that knows what works for them.
