Although I was never a big fan of Ross from Friends, there was one particular episode where I was 100% on his side. And that was when he flew into a rage when one of his coworkers ate his special sandwich and threw part of it away when he couldn't finish it.
No matter how good it may look or smell, I'm a firm believer in the sacred rule that you don't mess with another person's food. Whether it's their lunch or a snack on their desk, there's no reason for me to think that I have any business eating it until it's explicitly offered to me.
But as too many of us know, not everyone feels the same way and until she did something about it, one woman had to deal with a brazen office thief who was even more audacious than Ross' coworker.
