What do you think a lady would have said if it was a man standing there and when she went for the ladies room he told her to wait because there’s a line? No matter what you want to claim, we all know the truth of it. I have no problem if we want to treat all lockable single public restrooms as unisex, I can live with it. But I do have a problem if we are expected to treat all such restrooms as usable by woman, but only those marked as Men as usable by men.
