lol - probally not 5+ hours when the store is busy but you can definitely talk to him. The rest of the staff is pretty well versed in all Apple although each one has a particular subject they love... for example you want a gammer? Talk to Courtney.
We are waiting for Apple to send us a new campus rep who's whole job is talking all Apple all the time. Unfortunately the last one left us after getting his PHD.
I'm not 100% sure but they may still be looking for Apple reps... if you have it in you to talk about Apples for 5 hours straight this may be a perfect part time job while you're in school.
