Menace to Society

I work with many eccentric people, one woman in particular who is slightly mad. She is often found grumbling to herself and talking on the phone to her dogs. Today at work she came to my part of cubical land and began screaming at us that the Diet Coke she had purchased just minutes before, and had left on the table in the staff lounge, had disappeared. I am not sure if she expected us to dust for prints or what, but moments later, the following note appeared on a sign on the Coke machine.

Ummm..yeah...
