Beautiful view of the top of Monte Brè. And he's right @kus-knee nowadays it's almost mission impossible to get a clean public bath but the need makes us use it. The cleaning of this bathroom that you mentions is due to the note they put on the wall where he says to leave this bathroom as you would like to find it.
Even if you do not believe it, a simple note can make you act differently, since it says something similar to these "Do not do what you do not like that they do to you".
The natives of Monte Brè are very obedient when it comes to keeping everything clean and tidy.
Yes perhaps the sign helps.
