Outdoor restroom -- the best I have ever seen, June 2024

I saw this outdoor restroom setup in Geneva, Switzerland.
As you watch this video, you can understand why I consider it to be the best outdoor restroom I have ever seen.
As I was getting to the door of the restroom, and going Inside, I was saying out loud, comments about “payment.” Yet there was no payment needed to use those EXCELLENT restrooms.
What was that all about?
All to often, to use restrooms in Europe, you have to “pay” to use the facilities. Sometimes, it is “exact change” needed - and you never know until you get there, what coins will be needed. And sometimes you are up against a locked door, and the only way in - is exact change. And no human to assist you, to help you get the correct change.
Yet paying money - does not mean it will be “clean.” Sometimes it is “too expensive and too dirty.”
In this case - the restrooms were EXCELLENT and high tech. But no payment needed.
