Demanding passengers are nothing new to flight attendants; they're an occupational hazard. However one veteran stewardess was left speechless when she was working the first class section of a 767 flight from Atlanta by one passenger's cheek. After the safety briefing he called her over and asked to have some of the oxygen they'd just been learning about.
The flight attendant explained that the supplementary oxygen is for emergency use, but she was concerned about his wellbeing, asked him what was wrong and told him that he could leave the plane before takeoff if he had a problem. "Oh no" he replied "I just have a cold and thought some of that extra oxygen I saw on the video might help it."
