Rwy in Sight,
""No you will create a panic among passengers and you don't know anything about planes so don't annoy me"
If it was made into a brief feature sometime during the flight, maybe that mentality could be changed.
If you were on my flight, I'd certainly let you try it on, but maybe ask you to come to a galley area out of sight of other passengers. The last thing we need is a hundred other people thinking something's up, grabbing their life jackets and causing panic. It's enough panic when we run out of chicken!
