I get annoyed when Government is pushy, rude and aggressive

This is admittedly a fairly minor example, but it genuinely irritates me. And it’s by no means the first letter from HMRC that’s done the same.¬†Click for a bigger version. For the most part, I find that ensuring my business complies with all the Government’s requirements to file and pay things is a huge pain in the arse. I do most of it myself, I try to get it right and mostly succeed, and when there have been mistakes they’ve always been genuine. So, when I get letters threatening me with penalties if I cease to do something I’ve been doing all along, I get annoyed. It’s unnecessary. I wouldn’t ever send a letter like this to a client or a supplier unless sorely provoked. So why is it HMRC’s default tone of voice? Why can’t Government talk like a human?
