## The job. Deliberately, precisely annoying.
##
## Stations sit in the world (a desk, the photocopier). You walk up, press E, and get
## locked in place doing something mundane — because you ARE at your desk, and being
## unable to walk away is part of it. Every station has a designed way of wasting your
## time, and every wasted second is fuel for Rage.
##
##   SPREADSHEET — enter a figure in a named cell. The selection silently jumps to a
##                 neighbouring cell partway through. Commit without noticing and the
##                 figure lands in the wrong cell and you start again. This one is the
##                 whole thesis of the game in about forty lines.
##   COPIER ...... run a copy job. It jams. Clearing it needs the RIGHT tray, named in
##                 tiny text, and the trays are not numbered in a sensible order.
##
## Completing work pays WAGES and soothes the meter a little — never quite enough.
##
