And quite averse/backwater (choose your version) on using debit/credit cards. Which is mindblowing from my Easter European perspective. I didn't use cash in a decade.
Unfortunately that's much less the case since COVID. Not looking forward to have more and more placed that only take panopticon-payments.
That has pretty much changed now. I rarely use cash in Berlin. About 2-3 years already...
That reminds me when I was in Schleswig (lovely town) on my way to Denmark. And I wanted to pay for 1 day stay, lady that had (a really nice) apartment said that unfortunately her terminal doesn't accept international debit/credit cards (wild! and probably not true) and I had to hunt for an ATM machine to get some cash. It was 13 years ago, I remember I was so surprised that the west is so far back behind us.
Berlin is very different from the rest of Germany.
But not how you think, in this instance. I think Berlin has more places of questionable legality which require cash for presumably tax avoidance reasons.
germany had bank transfers as the norm when the US still fiddled around with paper cheques.
