Ever since Gordon Ramsay said that he would never (ever, ever, ever) eat plane food, we've been hesitant to pick up a fork on board a flight.
"There's no fucking way I eat on planes," he told Refinery29. "I worked for airlines for ten years, so I know where this food's been and where it goes, and how long it took before it got on board."
But if having to fast for hours on a flight weren't bad enough (although Gordon suggests eating a light meal of cheese and ham before takeoff), we now might have to go caffeine-free, too.
Flight attendants have been sharing the surprising facts of air travel that none of us (probably) knew—and one in particular will make you view the drinks trolley in a whole new light.
One flight attendant told Business Insider: "Flight attendants will not drink hot water on the plane. They will not drink plain coffee, and they will not drink plain tea."
And that's because not even the cabin crew know the cleaning schedule for the tanks where the water is kept. In fact, tests in 2013 found a high percentage of airplanes had bacteria in the water served on board.
So next time you spot a member of cabin crew purchasing a cup of coffee before boarding a flight, you know why. And you might want to do the same.
