That’s interesting because psychologically spending cash is supposed to be harder and so you think more about what you spend it on. However, if you dislike change (which I do too) maybe we spend it to get rid of it and with your card you only spend what you need to?
As for being cashless, I use cards when I can for lots of reasons, but I don’t want to see cash disappear and the recent Visa outage (which didn’t affect me at the time) actually caused me to withdraw more cash just in case a similar incident happened again and lasted days (unlikely, but who knows?).
The other extreme would be mainly using cash, and I wonder what problems that might cause. I guess “the system” just changes over time according to how people behave, and any shock to that system is disruptive.
