I am the opposite. I rarely carry more than the equivalent of £25 in cash.
Whilst cash is overrated (other than for money laundering and tax evasion) I would not wish to lose the option of being able to pay by cash - even though it is a more expensive commodity to handle.
My daughter doesn't carry any cash (except when in Thailand) and she has never had a problem. On a couple of occasions I have had cash, but no card on me, and I have not been able to pay with it. One was a pub in the Cotswolds and the other was easyJet......CV19 gave these airlines the opportunity to dispense with the messy business of handling cash.
