Gateshead woman with alopecia accused of being male while using female toilet at Tesco
(www.chroniclelive.co.uk)
The SEATAC airport has a few non-gendered restrooms and they're pretty nice. There's a big shared area with sinks, a wall of "stalls" (really fully enclosed toilet rooms, no panel gaps and floor to ceiling doors), and a separate room off in the back with urinals (and an automatic sliding door). Kinda seems like a pretty good solution all around.
