There is a TALL WINDOW in the booth. On the other side is your spectator, a MANNERLY HIGHBROW. He seems to have been waiting here patiently for a while.
There does not appear to be any glass in the window. On the other side, a coin-operated meter ticks down. The Highbrow has likely supplied it with a spondulick or two for his viewing pleasure.
There is a lovely mural on the wall beside you.
