That is another problem.yep people going out with no money in the bank thinking there wages have gone in on a friday (but havent) 3 contactless payments a day over weekend and 9 overdraft charges waiting for them which they might not know about till next statement
The major one is people spending beyond their means because they have a magic plastic card that allows them to.
I know many young people in their 30s with a £50k+ job who struggle to save money for a house deposit.
Some of them in a relationship with a combined income of £100k+.
They keep on spending by card and don't realise how much money they waste on things they would never buy if they had to part with banknotes.
