Aw come on Mac the Knife, where do yo think the water in the water cooler comes from? There's only one water source on an aeroplane and Lou Scannon is right, you wouldn't drink any of it if you could see inside the works...
BTW, the guy who drives the water cart and tops up the water is often the same man who drives the honeycart. Its generally good advice never to shake hands with a man who has green fingernails
