There is a part in Trevor Noah’s autobiography- born a crime- which is about growing up in apartheid South Africa, where his dad has a restaurant that is special because it has the permits to serve all races: Black, white, “coloured” and “Chinese” aka “none of the above.” It was very unusual, most places were only for one race.
But the officials got tired of having an unsegregated restaurant so they decreed that even if a place had a permit serve all races together, the bathrooms still had to be segregated.
Not having space in the restaurant for eight separate restrooms, he closed up shop.
