What's That No.6 Up To?

 "These are your papers Number Six. If you just sign at the bottom, the trucks all yours for a weeks hire."
   "200 Work Units, that's a bit steep!"
   "It's the going rate Number Six."
    "It says here that I'm liable for any damage, and have to return it with the same amount of fuel in the tank I start with."
    "Yes, the tanks half full, and if you want to make a one off payment of 150 Work Units, that will insure you against any accidents to the truck"
    "Don't you hire proper cars?"
    "There's no call for them, but they're better than walking."
    "You're sure about that are you?"
