As a principal I boycott places that only accepts cash in Berlin. There is absolutely no reason for them to accept money only in cash in 2026, except for tax evasion and money laundering
When I was young, cash was beloved by some as a matter of principle because of the fact you didn't need any authority's permission to accept it; coupled with its anonymity.
If you were running the city's only LGBT bookshop, you didn't want your till full of signed, dated checks - and card processors wouldn't do business with you even if you wanted to accept cards.
Stalkers.
Abusive ex’s.
And if you think it’s assholes targeted this way, look at all the women being stalked via flock by cops.
And if you think finances aren’t abused the same way, why do you think the Germans are so worked up about this? The fucking stasi.
A certain type of person will use literally anything they can find against you, including to harass you if they literally can’t find anything you did wrong.
And what better for them than a nice list of all the places and people you have some kind of important vendor or business relationship with - which is why there is money changing hands.
Grocery stores. Gas stations/subway fees, rental payments or mortgage payments. restaurants, gifts or family transfers, work, you name it.
Also, ask an older German if you think I’m kidding.
I used to go to a bar in Copenhagen with that principle.
The bar with the privacy principle didn't accept cards, and had a sign to that effect on the bar.
