It's things like this why we installed security cameras over the fridges in our break room. And sadly, yes.. we have had to fire idiots for stealing lunches.
What about Hot Pockets? Death penalty is advisable for stealing those at the work place and not returning them in less than 2 (two) work days. Me thinks they place some unknown chemical inside which renders them viciously addictive.
Should've just waited until both were stolen and posted a note saying "Thanks for stealing my Lean Pockets. Did you notice a semen-flavored aftertaste to that second one?"
I worked with a guy who planted frosted a frosted cake trap in the refrigerator. The frosting had a nearly-impossible-to-remove blue dye in it. When someone took the cake, later he posted to the department forum online that we should look out for someone with blue on their hands and face.
