Sometimes an Apple Store can get comical if you just want to go in and buy a product. A nice worker who is emphatically not willing to actually sell you anything advises how to get your name on the queue, at which point you have to stand next to that table until someone frees up from some other endless sale.

I guess that's why they introduced the "buy online and just take it and leave" model, so you don't have to deal with anyone, but it doesn't work for stuff in the back room.
