There is one drink that tourists should avoid ordering during the flight if they do not want to get on the “black lists” of flight attendants. These are carbonated beverages, including dietary cola.
It turns out that passengers who ask for a circle on board the plane, become unpleasant for flight attendants because of the specifics of the drink. Bubbles and foam formed during pouring, do not allow you to quickly serve the tourist. The soft drink is especially fizzy in the air because the lower air pressure in the cabin means that carbon dioxide is released more easily. And time for flight crew is valuable because they are guided by a regulated schedule.
In fact, in the time it takes to fill one lap, a flight attendant could also serve three other passengers. “As you may know, the pressure in the cabin is not to sea level, but the equivalent of more than two thousand meters. This means that some passengers may feel slightly dizzy or that alcohol affects them almost twice as much as on the ground. It also means that soft drinks foam much more when poured out of jars, and the worst culprit is dietary coca. I have to sit and wait for the bubbles to burst before I can continue pouring. If all 3 passengers ask for a diet, I often make them start drinking foam at once, then take three more orders for drinks, serve them, and then return to the tourist with a diet, “- said the publication of one of the stewardesses.
Dietary circles are not the only beverage to be avoided in flight, although one crew member said it was also wise to avoid tea and coffee. Tanks with hot water on board the aircraft are rarely washed, so the water may not be completely clean.
