Sometimes in the past pilots would start the APU to brew a pot, sometimes for one cup, then shut it down. Anyone venture a guess as to how much this one cup cost to brew? With fuel used and one more click in the start up wear cycle I'd be curious.
Sometimes we can poach a Starbucks filter pack off a caterer in an outstation (happened recently) so someone is serving Starbucks. I've also seen Dunkin' Donuts filter packs. I don't care for the corporate monster Starbucks has become but I love their coffee.
