cash still exists…
I bought gas for neighbours the other day, at Carrefour, in our nearest town.
I paid at the point of sale… and they paid me later.
One gave me a cheque and the other gave me cash, which she’d got from our village Banque Postale.
As it happens… I’d tried to pay for the gas bottles with my CA Debit Card, but had to go home for my cheque book… since neither of the card readers would work.
When I returned with my CBook, the place was packed and people were scrabbling through their handbags/wallets.
The turmoil went on all day…
I was not the only “trusted” customer who was allowed to take goods on the promise of returning with another means of payment.
