I went 85 miles in one direction to do a shift, only to have to turn around and go home after one hour because the originally scheduled nurse decided to show up. I decided that I would no longer be so accommodating. My gas tank was dangerously low for me to have been doing that when I had no money for gas. On a regular basis I had a regular case that was 35 miles away. My agency paid me mileage plus a higher hourly rate for that one, because nobody ever wanted to work there. I try to keep my driving to 20 miles in one direction.
