I mean it's not like foreigners are blocked from using cash at those stores. And if they prefer cards, it's not like the stores that used to accept them stopped accepting them.
They were nice enough and gave the pastry for free because they tried everything to charge the card but it didn’t work. They were embarrassed about the whole thing and were just like… please leave.
That being said, the US is a dinosaur when it comes to payments.
I agree that a lot of businesses now actively don't manage cash as they used to earlier... it's very difficult to get low-value notes as the central bank seems to be slowly reducing the supply by not printing as per demand.
Yes acceptance may have gone up, but I think thats a side effect of normalizing digital transactions popularized by UPI.
