I acknowledged this point but if you have any memory of the Tube prior
to zonal fares and I just about do then the old set up had arrays of
free standing single fare machine with huge signs above them saying
which stations for that fare. If you were very lucky you had a machine
with 10 buttons on it.

Also, IIRC, there were some larger machines which had a button for
every LUL station.
