This is an interesting point to ponder... Why is it that Seattle, a thriving metropolis of over 3.4 million souls in its metropolitan area, cannot install and maintain a public toilet, yet Paris, a thriving metropolis of over 10 million souls in its metropolitan area, can and indeed does install and maintain publicly available, pay-to-poo, self-cleansing toilets? I have used them, and they are by no means disgusting, gross, nor vandalized. What are we doing wrong here???
