I'm looking at an optional equipment list for a large cabin business jet as I'm typing this. An additional coffee maker runs $29,800 on this particular airplane.
A few other points of comparison:
Exchanging two TIA coffeemakers for one Iacobucci coffemaker and one espresso machine costs $59,000 on another bizjet.
Exchanging one coffeemaker for one espresso maker costs $11,000 on a different plane.
