Cash-only places are less common than they used to be, but there are still some really popular places to eat near me. And they’re popular for a good reason: they provide excellent food/service, and delivery services can’t insert themselves into the business model. It means I have to pass an ATM that day, but it’s a perfectly viable model.
If I’m going to a place called no screens cafe, I’d personally appreciate the complete commitment to the endeavor. If nothing else, it’s an invitation to ponder the frictionless ways we part with our money almost everywhere else.
Comparing “cash only” to “aggressive TSA” seems like a rather stretched analogy.
