That's interesting, here in Germany a 50€ note is very common, a 100€ note is not that common but people do use it from time to time, we also have a 200€ note that is definetly rare and then there even was a 500€ note which is basically extinct by now.

But we probably also use more cash here, I've never heard of a place here that doesn't accept cash, only of places that don't accept cards.
