Even in cities there are so many edible plants. Started eating the fruit of a random tree next to the sidewalk whren I found out that it is a cherry plum.
That's actually not the real German law. The actual law is called Rindfleischettiketierungsüberwachungsaufgabenübertragungsgesetz. Or short: RflEttÜAÜG. It was part of an act called Rinderkennzeichnungs- und Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz (RkReÜAÜG). But sadly it was abandoned in 2013. But we have a longer one, the Grundstücksverkehrsgenehmigungszuständigkeitsübertragungsverordnung (GrundVZÜV).
Example: Some homeless using this toilet, looking at the wall and reading that they can/should just be rich instead of being poor and that they easily can change their life.
Just say "Yes" and forget even about that.
