I can't speak for Apple, but something I was told at GNC that shocked me about the way companies might view their workers is that I, as a white male employee that enjoyed exercise, was always under more suspicion of theft than any customer would be. My manager straight up told me this, there wasn't any inference on my part nor was this some subtle implication. I understand they're different companies and different markets, but now I typically assume that most companies are more suspicious of their employees (the people who spend so much time in the store, who have a better knowledge of security than the average customer, who know what products usually go missing organically, what times someone is likely to be looking at them, etc) than the average random stranger who walks in.
I managed inventory at an Apple store and most of our policies was related to this risk. Since as a employee I'm able to mark a product as unsellable its gives the employee a lot of power to try to steal. Thats why if you look at a stores trash you will NEVER see a Apple product. Everything was sent back to one of the warehouses. even damaged cables. A bad employee can steal a lot more than any single customer. Apple just tries to be nicer about it ... positive intent and all that jazz. ....Hell the trash was the only security check that my store did.
