Thinking about being a stocker at walmart!?

I am 17 will be 18 in july and i wanted to know can a 17 year old be a stocker for walmart? because i know they have that box crusher which u cant use unless ur 18 but i heard u can put boxes somewhere and someone else will crush them..is this true and if you have worked or do work as a stocker how is it? Besides crappy...cause most jobs are...
