Sadly, the shine chairs, which were originally right outside the barber shop, were long gone by the time Union Station was changed from incipient ruin to bi-state tax-funded white elephant. The only remaining evidence of the barber shop are rings on the floor where the barber chairs once stood. (You can see the circles in the short hallway on the main level leading to the restrooms and in the mens' restroom as well. I haven't visited the ladies' room, yet.)
Thus spake the rabbit.
