Spending time in Europe has wildly opened my mind to new cultures, mindsets, life concepts and behaviors. One of them being trust — how governments (refer to Germany and Denmark) trust that people will behave accordingly when in the streets, shopping around, having drinks, and most importantly, when using public services such as transportation (buses, trains, metros).
There is no need to always have officers checking whether people bought their tickets. Things are based on trust, knowing people will act like adults respecting rules and paying for their ticket because they’re using public services. Simple, right? Treat people like adults and behavior will follow.
The more rules you put, the more likely people will want to break them.
