Annoying to get to since its in a mall, but there isn't an Apple store in the Phoenix Metro area that isn't inside a mall. If valet parking is your thing it's even easier to get to.
The service is a s expected. The atmosphere is as programmed by the Apple programmers. The employees wear blue shirts (red ones at Christmas time).
If you want a Genius appointment and have and iPhone or other Apple device, use the Apple Store App. You can book the appointment in advance and check-in using the App when you walk into the store. This allows you to do all of this without talking to anybody (I don't know why Apple doesn't want you to interact with people but hey they created this "atmosphere").
When your "Genius" becomes available your phone will tell you his/her name and that they are ready (Now you can actually talk to somebody).
You can also use the app to buy things off the shelf and walk out of the store (again without talking to anybody). Maybe Apple is just anti-social. Maybe I was just being anti-social.
I got my answer from the "Genius" and I was on my way.
