Growing up, I knew a guy named Clark. He ran a barber shop and he drove a school bus and he did leather work in the back room of his barber shop during slow times and he had a soda machine in his barber shop.
Restocking was a matter of getting bottles of soda out of stacks of supplies in the back room where his leather working stuff was. I know because my parents had a store next door for a while and I sometimes restocked his machine when he was too busy to get to it just to have something to do while bored out of my mind hanging at my parent's store.
I wrote about that once, probably badly:
