INPUT: The swinging of the kitchen door (proxy for dishes removed from the kitchen) + number of orders being placed + signal from apron when chefs are too stressed

OUTPUT: Signal to apron when there is a lull (back log is cleared and it's OK to take a Breather) + opening and closing of the door aperture (aperture closes = high stress, don't bug the chefs / aperture opens = lull, OK for front end staff to come back and bug the chefs)

INPUT: Moments of inactivity (event sent by The Signal)

OUTPUT: Small fan, DC motor powered head massager (with manual override switch)
