A few weeks ago, I went to a RSL while I was waiting for a mate. I ordered a beer for $4 and went to pay by card. The bartender looked at me weird and said "You're not paying by card". I asked if there was a minimum and he said "For something this small, you're not paying card". The RSL accepted EFTPOS, Mastercard and VISA since their were signs and stickers on the registers. Luckily, I had a few churchies in my pocket to pay for it.
I've rarely carried cash since I mainly pay for everything by card. I understand if a small mum and dad shop or small restaurant doesn't accept card but for an RSL, I'd except that they'd be happy to take card for any purchase.
So the question is for the ozbargainers: Do you carry cash?
Jokes on them and you: customers paying with cash spend less than customers paying with oplastic cards.
