Christep,
There are "few" things pax are briefed on only when circumstances arise. Otherwise:
a) Safety Demo will last forever (honestly, if we have to instruct pax on all we know and all they'll need to do in case of this or that or the other... Just consider an initial course last in average 5 weeks!)
b) Briefing card will be an encyclopedia
c) Average pax reaction
... most of them hardly listen or care about basic safety briefing and demo anyway!
Now, don't get me wrong, but I believe that you approched us in the wrong way, and with the wrong attitude.
As I see things you claimed to know as much as one of us do as "you flown as much hours as us" ....
Pax at the end of the day pay my wages, fair enough. I will treat them with respect, but I expect to be treated with respect as well.
They pay my wages, and I am there to look after their safety (first at all). Both with the knowledge I've gain over all those years and by training new cabin crew to be confident in SEPs.
Deep down I am a very good person, althought well known for having "a bit" of a strong personality
If you have any questions regarding Flight Safety I am sure all my wonderful PPrUNe team and myself will be more than pleased to give you an explanation.
Just remember to give us the credit we all deserve, and to approch us in a different way....
And as someone very wise said.....
here to save ur @ss, not to kiss it
