Pizza Anyone?

This aging fellow lives in a rooming house in a young area with lots of Pizza delivers. I have an outside entry to my room which of course lacks an address which has been frequently knocked on by pizza pushers who, unable to find their address assume it to be a door without one. So I have put up a sign reading, This room occupied by an old curmudgeon who didn't order the dang pizza."

Now the idiots knock and ask directions!
