Everyone's encountered their share of food problems at work, whether it's playing Tetris in the office fridge to find a safe space for your sandwich, or searching for the source of the mysterious smell permeating the break room. But above all, the worst offense someone can commit is taking food from the communal fridge that doesn't belong to them.

One woman, who was the victim of office fridge thievery, decided to take matters into her own hands. When she noticed her personal coffee creamer was dwindling quicker than it should be, she filled the bottle with her own breast milk and left it in the fridge for a week before revealing her devious prank.
