Credit only is becoming more and more popular, usually in more affluent areas where most or all of the customers can be expected to have a credit or debit card. I think it just depends on where you are and who your customers are. But if most of your customers pay with credit cards anyway, then there are a lot of good reasons not to mess around with cash.
Credit card processing is pretty easy, convenient, safe, and inexpensive for businesses these days. Handling cash is inconvenient, time consuming, expensive, and potentially dangerous depending on where you are and how much cash business you do.
I have gone to an Amazon store, but I didn’t buy anything.
Apple store is probably the same.
I understand everything you say and agree. Credit also gives rewards, so for years I’ve bought almost everything with a card.
Pay it off every month.
But, still, I’ve never seen a no cash accepted store. And there are still a fair amount of cash only joints.
