@TravellingMan22 , I agree.
Yes Spain, as with many other countries,
used to be a cash society - and in some smaller villages it's still very much is. However as we have discussed here numerous times on the forum COVID changed all of that. Or, perhaps more to the point, increased the speed at which that change was already happening.
Yes, there are costs to a business associated with accepting cards. Those costs have decreased significantly, which has increased acceptance.There are also significant benefits. Hence why so many small businesses in Spain now also accept cards.
There are also costs - and significant risk - to handling cash.
A business would not offer a facility if it did not make economic sense to them. Which is why in some cases they set a lower limit (often €10, occasionally €30 - which is the point in Spain that they legally
must offer an alternative method of payment)
Regardless of which method you choose to use those costs are built into the price that you pay.
I have mentioned on a previous thread that I had a conversation with a cafe owner on the Primitivo last year. He told me it was definitely preferable for him to do the majority of his transactions as card, as all of his payments (to his staff, suppliers etc) were electronic. There was no bank in the village and it meant he didn't have to regularly leave town to do his banking. It also made it significantly easier from a tax perspective. Let alone the time-savings. And, as is often said in business - time is money.
Plus of course it improves security - less chance of theft, whether by staff or outsiders.
Personally I always try to have at least a little cash on me - if for no other reason than to be able to give somebody a tip if I feel like it!
