Go to a public school in berlin, look at the toilets. Chances are very high they might be defect, stink and malfunctioning. I worked as a special eds teacher in Neukölln. We're supposed to train our students how to use the toilet. Half of the time the toilets in the first floor were broken. That means me had to stand in line for restrooms instead of doing some work. When the toilets got repaired after half a year the toilets in the basement broke down. Our students became very good at waiting in line.
Now i work in a school in the southwest of germany. If a toilet breaks down, chances are it will be repaired on the same day. If they need an external contractor in will take one day.
All of the students live in germany. Yet one get clean, functioning toilets, the others not.
(Fun fact: Berlin paid for my education, now Baden-Württenberg gets a university-trained teacher for free...)
