I overheard a very cute conversation on the train a few days ago between three young teenage girls. It went something like this.
"So, he asked me to pay in cash, and I said, I don't have cash, I only have coins"
"But coins are cash!"
"No they're not! Notes are cash and EFTPos is cash. Coins are coins"
"Coins are a pain. Why would you use coins? EFTPos is best. That's real cash"
All I can do is feel old.
