Honey,
I like your style. Like I used to tell some of my male co-workers - "I'm not your mother and I'm not your wife and even if I were, I'd still tell you to get off your rear and clean up your own mess."
He who made it shall clean it.
However, in order to keep the peace (to a certain extent), I would just go ahead and remove the nice dishes without notice and when they asked why, tell them plain and simple that apparently certain people couldn't handle the repsponsilibity of cleaning up after themselves.
Just my $.02.
Michelle
