There's a very common behavior, among bureaucrats disdainful of the public (you can fill in your own opinion regarding the percentage). When no citizens reply to their obscure required public legal notices and announcements, they smirk. As if to say "there's nothing wrong with what we're doing: no one complained." Or perhaps to say "people are so dumb and lazy, they don't even want to be heard". In anycase, there's no good reason for the grin. It is in fact the exact grin of a criminal who's just pulled a fast one.
I don't know why they call these people "public servants". Well, actually, I do. It is intended to mislead. Like the "Department of Defense", which is obviously focussed entirely upon aggression. Not unlike most public servants.
