Cornishflyer's post doesn't surprise me (althought it does disgust me). Aside from businessmen, many of whom think all safety regs do not apply to them, I have noticed that parents can be amonst thge worst.
Having had much time to think about such things I have concluded that a high proprortion of parents who take young children on flights (esp holiday flights) are very selfish, because the flight is for their benefit not their childrens (for whom a flight is hell and who would just as rather hoiday in cornwall as in the caribbean for example). Thus such people, beoing selfish, are more likely to react badly to safety instructions.
Of course they say the flight is so that Arabella can learn about different cultures or whatever. No, its so you can soak up some sun
I appreciate this is a sweeping generalisation so please don't be offended if you have taken your children on a flight and this doesn't apply to you, but I do believe there is an element of truth in it
