Must be a Millennial
Cashless in 10 years? That's the sort of prediction a naive, sheltered millennial might make. Here in the real world there is still a significant minority of people who do everything in cash, and an even bigger minority who use cheques but don't, and probably never will, use online banking. Quite a few of them are my clients. They won't all have died off in 10 years, I'm glad to say.
I personally use cash for most of my physical shopping (petrol, supermarkets etc) - if I didn't I'd have to pay the crooks called bankers just to give them my cash for them to make money with. My business bank doesn't pay interest on balances under 1/4 million so no incentive there.
Even if all my clients paid direct, I'd still use cash if only to reduce my data footprint, but I'd have to start going to cash machines to get it instead.
