Although it was inconvenient to us, because I didn’t know, I was very pleased to see that many restaurants and cafés wouldn’t take payment by card. This included the restaurant in the Geneva beach complex. So cash was needed, but, I hope, less of it because the cafés wouldn’t have to pay bank commission.
It is wrong that shopkeepers have to take cards or lose business, and charge cash customers the same amount even though they have no commision to pay on the cash payment.
The customer should pay the commission, and then they have the choice of giving some money to the banks or not. The same should apply to electronic payments like Paypal. The buyer should pay the commission.
