No, each receptacle screw had two hots and two neutrals on it respectively (2 hots on one screw, two neutrals on another screw).
Middle of the run receptacle (all four terminals used) with a "tap-off" or spur going to a socket in another room.
They simply added the new wire to the existing terminal screws!
This is a city owned building, see my post here: http://electrical-contractor.net/ubb/Forum1/HTML/002648.html
-- oh you did see it already.
I was also replacing the combination light switch/GFCI receptacle in the bathroom and discovered they used BX cable into a box with a clamp designed for NM (at least they used a red-devil to protect the wires)!!!
