I've put another nail into the pentagon it seems. What does that 770 mean on the bottom of the pinball machine? My guess is it is a reference to UFCW Local 770. Where that goes is interesting. The clues to this notion exist in smallish clues on several floors. What to take from this? The Farmer. Unionization gives strength and voice to the workers, but there is nothing without the Farmer. I believe this works with the "toilets theme" to produce the name John Farmer, the 16th century composer.
