First and foremost I was not the pilot
flying. I was the one montioring this guy trying to milk every penny out of a flight ignoring the common knowledge that slow airspeed that is degrading in mountain wave can be impossible to regain. So why not start out with a safe airspeed with a cushion especially if you're planning on sleeping. I don't care if you sleep, but don't make me clean up your messes because you want to make a couple extra dollars while snoozing. You're a tool if you disagree with that you ignoramus.
