I've taught little kids and I've also been a lifty, and I can say that without a doubt, I'd much rather teach then be a lifty.
Being a lifty kinda sucked, standing outside in the cold watching all these people have fun, shredding the pow... It was especially depressing when sitting at the top of the lift... If you like sitting in a hut watching the snow blow listening to music and watching your friends wave at you before they go rip lines.... depressing.
Teaching was more fun, you get some cool little kids sometimes, but it can really go either way, there are some brats for sure.
I would say be a busser, or a cashier in the caf. Rental tech would suck on days where you get elementary/highschool kids coming in.... but i dunno how often that really happens, never worked rentals.
