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 will care so much about that?"the driver answered .
"Look,the digits in the meter are still running when the car has stopped,"I pointed at the meter.
"Oh.yes.You've got a point here,In this case,time is money for both of us,"added the driver.
