Cash is actually increasing in popularity again. Hence there was a fuss at a supermarket recently where only one out of 4 ATM's was working. Customers were queuing.
I think millions are realising what a huge loss it would be if cash disappeared. Not to mention many young people and those hard up, much prefer cash, as they can't overspend.
Also - and I fall into this category - they resent being told what to do.
In the wake of the Nigel Farage debacle, it would seem that a large number of concerns are being de-banked because they deal in cash. Not sure whether they just get told "commercial reasons", or whether they are simply informed up front that from such and such a date, they can no longer pay their takings in cash, and must change in advance to keep their account.
