I've been using a contactless credit card for 95% of payments since about 2016. Before then I'd use card via chip & pin for most things still, but cash for fast food as it was a faff to type in my pin to pay for that kind of thing when there's people queuing behind you.
Haven't used cash primarily since 2003, as that's when signing for card payments (which I hated doing as I normally was carrying a ton of stuff) was dying out and chip & pin came in here.
I always keep some cash in my wallet in case I need a taxi or a tip or something. Don't want to use cards for that.
