Passive-Aggressive Sink Warning Sign (Multi-Color & Raised)

We all have that one co-worker who treats the sink at work like it's their sink at home and lets their dirty dishes sit in or around the sink for their spouse to clean. The only problem with that is if that spouse doesn't work where you do, those dishes will sit there until the heat death of the solar system. Send a clear message, and in a humorous way so that they don't confuse the sink at work with the one at home.
