I suspect at least some businesses everywhere in the US will move to this model in the next few years. Handling cash is a big logistical risk, and the only question is how many cash-only customers can you afford to turn away? And from my own non-coastal non-big-city observations, cash-only customers are fewer and fewer, and largely of demographics that some businesses (but not all) would be perfectly happy to have a reason to refuse service. But cash won't go away anytime soon. You just might have to skip dining at the latest fast-casual chain or indie coffeeshop to come to your town.
