The reason that buildings do this is archaic laws which require that they have to have X number of mens restrooms and women's restrooms per Y number of occupancy capacity. Unspecified single use bathrooms don't count towards these requirements.

Yes, the bathrooms are exactly the same. They both have a toilet, paper towel holder, sink, foam soap, trash, and nothing really else.

But until states start repealing outdated building requirements, this is the stupidity we have to deal with.

Like does my wife's OBs office really need two mens restrooms when there's only one male OB and all the receptionists, clinic manager, sonographers, medical assistants, nurses, PAs, midwives, and remainder of OBs are all women?
