On top you got a culture of being on time, which is prevalent everywhere, and you wait for stuff very seldomly, and only for a few minutes. Waiting for anything was one of my biggest irks in my home country, the fact that I can make an appointment, be there 5mins early, and get the service, blows my mind.
While some countries provide a non-binding translation for many things, someone could set the precedent in court that the English translation if relied on by enough people is somewhat binding or similar - Result would be two slightly different (mis-)understandings about the law, due process and bureaucracy from official sources. That could be have unforseen consequences.
Just because many people happen to speak English doesn't mean everyone has to.
