If possible look it up online. Waiting there can take a long time. Better you pretend to buy something then you get help right away. Also go during off hours for faster service
Should not take long at all if you go in person. The place is staffed. I unusually well staffed compared to most places these days. I guess you need to refer to these people by calling them "genius". Well I watched a live instructional seminar in there and can say they aren't all that. But they are there in numbers. Try calling a local store? Not sure how you would. Good luck though.
It's better if you went in person, I was on the phone for 25mintues
