Do Germans really count starting with the thumb? I (an American) find this very uncomfortable

You have probably seen the meme from Inglorious Bastards where an American spy is outed by ordering "three beers" and holding up his index, middle, and ring fingers. The Nazi agent recognizes him as a spy for not using the German way, which would be thumb, index and middle finger.

As an American, I've always done index, middle, and ring. When I try to make the gesture with my thumb, I find it very hard if not impossible to curl my ring finger down. Indeed, to make the "peace" V sign, I have to use my thumb to hold my ring finger down.

Do you guys just get used to it? Does doing it the "American way" feel weird to you? Or is this whole meme BS and Germans don't actually sign 3 like that?

EDIT: Is this sub always so active, or do y’all just have very strong opinions about counting? I’m at 72 comments as I type this and the thread is barely 10 minutes old…
