I actually am on the opposite end of the spectrum, I think cash is pointless, it’s less secure, less authentic and prone to issues. Just make the swap to digital or cards, most checking or savings accounts are 100% free, there’s better protections involved, you don’t need to worry about breaking large bills, don’t need to worry about the shop not having change, easy to track as it’s super easy to just look at your transaction history. Balance is super simple, instead of needing to count the cash I can just pull up the account.
It’s just easier. I think cash should be optional for establishments, it’s better for everyone involved both consumer and business.
