My coffee maker has a pinhole in the grinder. It was caused by the abrasive wear of crushed coffee beans. They slowly ate away at the hard plastic wall, and finally a pinhole formed, out of which fine grains of coffee spewed every time I made a fresh pot. It filled the gap between the housing and the wall of the coffee maker, with a fine dust of ground coffee and I wondered if I should just clean it out.
But another part of me said that I should let it go on compacting, getting harder and harder until at last it formed a brick that I could then grind up and smoke in a bong. And that’s when I knew I was addicted to coffee.
