I went to the Old Vic theatre last night and was pleased to see they have changed the signage on their toilets to mens, womens and then two separate unisex/accessible individual rooms with washing facilities and proper doors.
Last time I went there were very unclear signs with pictures, and words saying stuff like 4 stalls, 5 urinals. And in the women's toilets, some confused and embarrassed men who hadn't realised they were the women's toilets.
Hope the same is happening elsewhere and other venues are realising their attempts at right-on 'inclusivity' are a mistake and nearly everyone wants/needs/legally requires single sex toilets.
