When you are playing an egomaniac running a fantastical ship, you don't want him to be too suburban. Naturalism doesn't work on the high seas.
I worked at car washes - two or three different car washes. I worked at McDonald's and Wendy's, I worked as a dishwasher and as a telemarketer in two or three different places. I sold windows door-to-door and never once sold a window.
