Stupid Bosses

My ex boss had me driving every day to different jobsites saying that he would reimburse me for gas. He also had me do non-related work like mowing his lawn and what not. I have yet to recieve a payment, and it has been over a year now since I have worked for him. To be exact, I drove nearly 3500 miles for work purposes, not including home to work type driving, and wasted my hard earned money on gas on his behalf. $7.00 an hour does not work well with gas, or vehicle servicing costs, even when you are a DIYer.
