It’s my impression that at least in the German-speaking cantoons the Swiss are the most “rules are rules are rules” of the German-speaking people.
Had this happened in Britain, it would’ve been swept under the rug since over there de facto and probably since forever, the rules apply very differently depending on the “importance” of people. (In fact I wouldn’t at all be surprised if this was also happening in Britain and in there it was simply swept under the rug).
I don’t think “rules are rules are rules” is a generic “honor” thing, rather it’s the more specific norms of “social responsibility” (i.e. responsibility towards others).
