Indeed, i have seen a case whereby the driver has other jobs and investments, and he really does not need the driving gig. But his reason for doing it was that he loves driving so he is just doing it to kill timeunless the driver is doing some other side job about from driving then he can be reached on his boss but he is not doing any other side job and has not been edited any amount of money from a dead relative then I think the driver is possibly stealing from stores.
