This week I found myself in possession of a couple of crisp, crackling hundy notes - $100 of pure, unwrinkled buying power. Or so I thought.
In today's electronic world, our wallets are heavy with plastic instead of paper and it is not often that bank notes of any description, let alone the highest denominations, feature in day-to-day, non-drug related transactions.
Although I knew this to be true, I hadn't realised quite how difficult this made using my $100 notes, nor how confronted retailers would be when presented with it.
My first encounter came after seeing my chiropractor, where I proffered my hundy to pay for a $48 treatment.
The look on the receptionist's face when I presented the bill would not have looked much different had I given her a wet turd instead. Neither, apparently, were practical options for paying my bill. There simply wasn't the change.
