Seeing signs like the one below is always jarring. How could it not be? A hugely incongruous sight in any era, but surely even more so in a modern city, in 2019. And yet that said, as the services on offer are adult orientated, a lack of communication could obviously be a problem. An element that arguably makes it a little more complicated, and perhaps, at a push, not quite as clear cut as it initially appears.
So is it a grey area, perfectly okay perhaps, or without a doubt completely unacceptable?
