But if the store in question would accept cash, then it could at least server some of its customers. I expect it would not only be 15% of the customers. I would add those customers who are, you know, a little capable of adapting to circumstances and would actually go to their ATM to pick up some cash if they don't have any in their wallet. If not, I guess they don't need those groceries so urgently.
I think you're underestimating how little we use cash. There aren't even ATMs in some parts of town and there are plenty of villages without one for tens of miles. Nobody uses cash anymore. It's all either debit cards or direct transfers (either via and app or the bank.)
