I recently moved from the Netherlands, where card is overwhelmingly favoured (at least in Amsterdam and Den Haag, I've never been somewhere that doesn't take card and some places refuse cash) to Berlin, which I think is even more pro-cash than most of Germany. Cash is way slower, and I've now got a couple euros' worth of coppers that are utterly worthless because no-one's going to bother counting them out. In the Netherlands the smallest denomination of cents is 5, but you could live for years there and not know, because almost everywhere takes card (and most machines support contactless).
