As a german I have never seen this but whichever country is doing that has things figured out.
To be clear we do still have proper stalls, it’s just that bathrooms are always gendered unless it’s a really small place that only has one toilet in the first place.
I knew about the gap but… no indicator either??? Are they at least locked so the worst case scenario is thay awkward moment where you try to open a locked bathroom stall?
I’m planning on visiting next year so I guess I’ll see the reality of it. Maybe I’ll have to avoid public toilets even more than usual lol
