Just before lockdown started, I took £100 out of the Cashline. Up till last week, I still had some of the notes in my wallet. Only regular cash usage has been the couple of quid tip to Just Eat drivers. Yes I'm a fat bassa.
Ordering by app in a pub and having a pint of T delivered to your table is a revelation. However, I can see how folk easily lose track of their spending rather than limiting it to what cash they have taken out.
