It varies all the time, sometimes it's gas, sometimes it's cash, I've never done it , I mean in any good conscience, how could you keep a straight face and tell someone to go risk everything they have or may ever have to drive for the most exploitive company in the history of the US workforce for pennies. How do you sell someone on the idea to drive for 49 cents a mile and only about half of the miles will they have a rider and be paid ? Anyone that I associate with can translate that into 400 miles = $100 .
