One of the best "pineapple stories" . . . long ago, one of our clients was a local interisland airline. Like everyone else, they served pineapple juice onboard. Then one day, Boeing notified their customers that, based on some airframe inspections in Asia (they aslo served pineapple juice), the spillage was having an effect on the subfloors of the galley and service areas . . . so cut it out.
