When I was an student between my junior and senior undergraduate years, I worked a shit job in a Friendly's fast food restaurant. It was, as I say, a shit job, but we had some fun. After hours we would let in our friends, lock the doors, smoke pot, and gorge ourselves on ice cream. No matter how much we pilfered thus, we could not make a dent, a fact which struck us as hilarious as we continued to devour the cold sweet substance until satiation.
I was working in the back room one day when I suddenly found myself charged with the task of clearing handfuls of dishwater-logged coleslaw from the drain of an immense sink, as deep as my arm was long. Undignified and messy though the work was, I regarded it with equanimity because I understood that this was very probably the nadir of my employment career, and from this point forward things would improve. My optimistic intuition has proven correct, sort of. I have since had moments in my working life where I thought I might rather be back at Friendly's with the dishwater-logged coleslaw, but no moments quite as messy in the literal sense.
Besides this insight, there were other benefits to be gained from Friendly's. Early in my short career, one of the other employees explained to me how to replenish a paper napkin dispenser. My instinct told me to stuff it to capacity and beyond, so that refilling would be as infrequently necessary as possible, and began to do so. But my wiser colleague pointed out the correct way to fill a paper napkin dispenser: leave a little space towards the front. If you overstuff it, the napkins cannot easily be withdrawn cleanly, and the customer will inevitably pull not one or two napkins, but an entire cluster. You have surely noticed this yourself when dining at downscale establishments. Besides being wasteful, overstuffing has the ironic and paradoxical effect of making the Friendly's employee have to refill the dispenser sooner rather than later.
Everywhere you go, you see these dispensers overstuffed. Filling them properly is a lost art. Fortunately for me, I have not needed to apply my napkin-dispensing knowledge in the workplace, because as I said, the coleslaw prophecy has proven true. But it has given me the authority to second-guess paper-napkin-dispenser-fillers across the land.
