We had an a$$hole that would come into our office space to do work, and he would raid our refrigerator. I spoke to him many times and he still didn't listen. Well, we had doughnuts one morning, and we put a couple of drops of Visine on them. We worked in a secure area, and we had to open the doors for anyone coming in or leaving. We watched this a$$hole sh*t his pants as he was running to the restroom. He never touched anything in our fridge again.
