One unforeseen consequence of taking photos of a lot of public bathrooms is all of the strange conversations I have with people. I, of course, wait until any multi stall restroom is completely empty before photographing it, so in the meantime, I just oddly stand around as though I am waiting for something specific to happen. And conversely, when someone walks into a bathroom I am photographing I am at a loss of how to explain without sounding strange.
I do think it is a worthwhile pursuit, and in a way, a really interesting way to document places where I have gone camping or towns I just passed through.
