As the taxi came to a screeching halt at a traffic light, I asked the driver, "Do you agree that 'Time is money'?"
"Well, it's a very common saying. Who cares so much about that?" the driver answered.
"Look, the digits on the meter are still running even though the car has stopped," I said, pointing at the meter.
"Oh, yes. You've got a point there. In this case, time is money for both of us," the driver added.
