German here. What I understand is that we Germans use the folding technique instead of crumbling the paper. And we love our sweet 4 layered paper so everything is super soft down there. I can say growing up the first years of my life in the GDR with literal recycled paper as toilet paper, that I wouldn’t go back to that. But I see especially with kids etc that we overuse toilet paper. But I can only speak for my family. Toilet paper usage etc isn’t a dinner conversation topic.
