First real job - besides having a watermelon stand - was working as a helper/stocker at a video rental place. I think I was 'let go' from that job for refusing to sweep an aisle with a customer in it. My granny always taught me to do unto others as you would have them do unto you - and I wouldn't want someone sweeping me out of the aisle when I was trying to decide on a movie to rent.
I've also :
Worked as a cashier/janitor at a gas station - midnight to early am shift.
Inventory taker - going around with those hip-calculators taking inventory at gas stations, grocery stores and retail outlets.
Telemarketer - offering tickets to a country music concert for donations to a fire department.
Setup worker - installing shelves, aisles and such for a retail store - K-Mart if I recall.
