I'm often tempted to add to signs.. When I see "Wet Paint" I feel "This is not an instruction" would work well. To "This door is alarmed" perhaps "...why? What's happened to it?". I've often felt that the sign "We ask people to leave this kitchen as they would wish to find it." is a bit harsh. I can't afford to refit the whole thing in pleasant pine, stock it with state of the art appliances, cakes and coffee, then hire scantily clad blondes to dance i it all the time.
