I confess that I used to ignore the demonstration believing I know it all. Now I follow it as close as possible for two reasons:
The first is courtesy - one is amazed how much difference few years and a couple of good exemples (sp) can make; second is my profound belief that by watching it I shall not need it. So far so good!
What does drive me nuts (sp) at least on my part of the world is when a pax reads during the entire demostration only to pray - what's the term cross themselves (sp) as long as the a/c turn on the runway for the take off.
Now for the presenation part I think an appeal on courtesy or point blank explaining that understanding the demostration may signify the difference between life as usual and death or life as criple, would definitely attract the necessary attention.
Alternatevely and realizing that this sound sexist and degrading to othen human beings I think a demostration by an attractive and suitably dressed lady would definitely attract the needed attention.
I apologize in advance for those offened by the last paragraph....
