Discussion on question by dsollen: Would it be legal for a business to provide only unisex multi person restrooms for use?

@MonkeyZeus That's a different issue, though I think the real problem is being in the same room as a man, after all most porta potties have urinals in them and while people don't like using them for other valid reasons I've never heard anyone cite the urinal as the problem. Realistically convincing people from the USA to use same sex, multi person, restrooms would be quite a challenge.
