#62 Dirty Work For Clean Clothes
I had a landlord a few years back who was a bit of a slumlord. He had a coin-operated washer and dryer and one time, after he fixed the dryer, he forgot to put the screws back in place, leaving the main circuit board easily accessible.
After a quick Google search, I learned you could change the amount that the dryer charged by simply unplugging the circuit board and plugging it back in. I never told any other tenants but took advantage of this for the last few months that I lived there. I always worried he would notice that he was suddenly not making as much from the dryer as the washer but he never did. I think he was too lazy to bother noticing those sort of things.
