"You never have the right change for the meter"
The somewhat disturbing thing is the failure to context switch that I had reading this. It took me more than a minute to stop wondering what the exchange rate for yards to metres was at the retail level. And what the commission rate was.
"Excuse me, have you got change for a metre?"
"Sorry, I've only got a couple of decimetres..."
