I know there are some on here who say they never ever use cash. I don't know how they manage. Like most people I use a mixture of bards and cash.
So in the fortnight the times I have had to use cash are as follows.
Buying the Big Issue. I assume those who never use cash never buy the Big Issue.
Paying for drinks at a cash bar at a wedding. Very posh venue, but cash bar only, no cards.
Getting the bus into town. I live in a City where the buses only take cash or a bought bus card. I hardly ever use the bus, so no point buying a bus pass, so I used cash. You can not use a card.
Went to a local vintage fair today. This is a small fair and the best stalls are always some people who do this as a hobby/to make a bit of extra money, and none of them take cards. I assume because of the cost of taking cards.
Paid a tip by cash in a restaurant. I always pay tips in cash so servers get the whole amount. Even the best places take an admin fee.
By refusing to use cash I would have negatively affected my life this fortnight and not supported someone who is homeless.
