You are correct, that I cannot understand something that I've never seen, or even heard of. I've seen shitfaced people stumble into restrooms pretty frequently. I've never seen someone say "I know there is a toilet less than a block from here, but I'd rather piss on the wall!". But I hear the opposite all the time: "Man, I wish I didn't have to piss out here, but the nearest toilet is a mile away".
It is not feasible to blanket a city in toilets sufficiently to eliminate public urination...
I've had people knock on my door trying to push stuff that I even agree with: fixing climate change, helping the homeless, anti-trump stuff....
And I still want them to GTFO. If someone interrupts my day, I'm not gonna listen to their pitch at all. It has to be something important, and something that I can help with right now.

My superkey controls my OS (window-manager, music, launcher, brightness, etc).
My alt-key controls my tmux and browser
My ctrl-key controls the app (vim/bash/mpd)
