An Aer Lingus flight took off from Dublin to New York, when not long into the flight the stewardess nervously came onto the intercom
"Ladies and gentlemen, I'm extremely sorry but the catering company have made a huge mistake" she said. "120 people are on board, but they only gave us 80 meals, so we've decided anyone who gives up their meal to a hungry person will drink for free for the rest of the flight"
Several hours later she came onto the tannoy again
"Ladies and gentlemen we are now approaching New York, please fasten your seat belts and return your seat to the upright position, by the way, we've got 80 chicken dinners here if anyone's hungry"
