quaker?

Seen a truck this morning for a haulage company called Quaker Transport or something. So I'm assuming it's some kind of pacifist lorry driver.

On the side of the truck it says, "Give ya head a shake." On the back of the cab, only visible to drivers when he's not towing a trailer, it says, in script, "I don't give a shiny shit."

So now I'm thinking, a pacifist truck driver with attitude.
