Teaching Him A Lesson
Someone in my office would always crush lunches with his gigantic lunch box. Either he ate bricks or lead, I don’t know, but I always came to the office fridge and found that my lunch was in pieces. So, after three bouts of this, and numerous notes from myself and other colleagues, I decided to teach him a lesson—I carefully removed his lunch box, emptied the contents (a gigantic sandwich, a Twinkie, chips, some vegetable pieces, and a few other bits), and ran over them with my car. I carefully packed it back in and put it back.
He kept his lunch in a cooler by his cube from then on.
