Pose a question, expect a no-nonsense, factual answer. Don't be offended but appreciate the candor and brevity. Get back to being productive so you can leave for a timely Feierabend like everyone else.
To be fair, this would probably still be considered very unusual in Germany. You're not obligated to do a while song and dance, but uf you do this I would assume it's a very deadpan joke.
I was watching a YouTube video for Americans on what not to do when visiting Germany. I was thinking that I would love to live in Germany throughout the video for the reasons you stated.
Germans are indeed direct and that can be relieving for people who hate the small talk subtext of conversations. But even Germans have their pleasantries, especially in rural Southern Germany where you greet everyone you meet with "Servus!"
No, I stand by it.
And if it's reading comprehension you struggle with I'll reword it for you:
Germans have earned their reputation for being unusually robotic, cold, strict, pragmatic, etc.
There are still a lot of Germans that aren't like that, but these exceptions don't rule out the stereotype completely.
I'll add that this reputation might be due to how the German social strata is ordered, what kind of person succeeds, rises to the top, and interacts with other people abroad. It's not necessarily due to an overall difference in behavior broadly present in the total population.
It's like how Americans have a ridiculously low level off trust compared to other developed countries, and how Russian largely don't give a shit about anything beyond their doorstep. (Тебе больше всех надо?) Sure, generalizations can be unfair and at risk of being completely wrong, but I don't think this one is.
