was charged an extra $10 for waiting in the cab at walmart to have groceries loaded even when the cab driver had no one else who wanted a ride, when I knew what was going on I got the driver to let me out and pick me out later when the groceries from walmart gocery pickup order were ready sure it would cost more for a cab to wait on you like when I was waiting in TD lineup and was charged $5 for 10 min or more but to charge extra without saying so is unfair.
