For every person who says it's too easy to tap tap tap, there's probably another who says that they prefer card, because they have a list of transactions instead of taking out a note, breaking it, and the rest evaporating so they've spent £20 on little bits of they don't know what.
But in reality, this is not the issue, as the decision, and where you need to be mindful, is when you decide to make the purchase, not when you're paying for it.
If you think 'do I really need this coffee, can I wait until I get home, use something I already have' etc etc, then how you actually pay for it is irrelevant to the amount you spend.
But as well as the 'the banks are stealing all our money' conspiracy, there was also a revival of envelope budgeting via a TikTok craze because it allows you to buy pretty envelopes and make a nice video counting notes in each one for rent, electricity, food etc.
