There used to be public restrooms in New Orleans back in the early 1970’s. It is a bit of a problem when there is nowhere to go if you have to.
On the other side of the coin you can just do it French style and pee on the sidewalk. Yes, that’s exactly what I saw the very first time I went there.
Plus he French are not noted for brushing their teeth
Same thing when I was coming into VietNam in'69. A lady squatted and peed with people walking all around her.
A little culture shock for a bumpkin from Louisiana.
