> Germany is infamously almost cash-only.
Let's not exaggerate. While I am often enough exasperated at how often certain restaurants or bars will still only accept cash (or sometimes EC card), I'm still able to do about 90% of my transactions by card.
Interesting! As a tourist, almost all my transactions had to be cash: but ofc a tourist and a resident don't have the same spending patterns (mostly bars and restaurant for me)
In the US, cash-only businesses usually attract auditors from the IRS (or did, until they gutted the agency).
