There were two of them - while at home on summer break from college. This was mid-1980s. I just walked in to a local temp agency and said give me whatever you have.
Job #1: Graveyard shift at a swimming pool supply store. Unloading deliveries, cleaning up the store. Manager was a bozo - the one thing that sticks in my mind - he would have us sweeping the carpets. It's the cheap indoor/outdoor carpeting. Why don't we simply vacuum? Why should I care, they're paying.
Job #2: Graveyard shift at an injection molding plant. You see old black and white photos of folks working with these big machines in a cavernous sweatshop - that's what it was like. It was 8 hours straight of monotonous work. Summer nights at 75-85 degrees no AC just some fans - so it's above 100 in the factory. Same routine over and over for 8 hours...Close the door on the machine, hit a button, wait a certain amount of time, pull the stuff out, clean up the burrs the machine would leave, wait about a minute for the plastic to harden sufficiently, stack them, then repeat the process. I turned it in to a game of sorts, trying to do it as efficiently as possible and as many as I could in a single shift. I know the floor manager took notice as nobody came close to what I would do in a shift. I was usually working on the machine that made bread trays and another for the canister that would go in home ice cream machines (metal canister with plastic piece in the bottom that lets the machine spin it).
Best I can remember, these each paid about $4.50/hour.
