Some gentle people in San Francisco do not have flush toilets, while those who have won life’s lottery do.
The only fair solution is to enact legislation prohibiting the ownership and use of toilets.
Only when there are no toilets will the brutalizing inequity of of the plumbed/unplumbed finally put people in motion
Just so happens that I know how to build outhouses, one holers, and the Cadillac 2 holers for the really friendly folks. Pass that law and I will head to SF.
