I've worked retail in my college days, mostly at stores pitching products I didn't personally really like. Yes Christmas time is busy and you spend a lot of time on your feet.
Too bad Apple wasn't in the 90s what they are today. If I'm going to work retail, an Apple store would be my first pick. There is a certain intrinsic gratification helping someone purchase something they will enjoy. And, that only comes with selling products you like.
