On Saturday I was at an outdoor event where the Internet signal was poor so everyone had to use cash - they had been pre-warned this would be the case.
I left a cash tip in a cafe on Tuesday.
Parked in a pay and display car park in mid Wales the weekend before last where there was no other option but to pay by cash.
Saw a SM post yesterday for a big outdoor event locally which takes place at the weekend. You can't take your own alcohol into the event (but picnics allowed ) and the announcement said that the official bar at the event will only take card payments. There was absolute outrage in the comments under the post about being unable to use cash, which really surprised me.
