Arty, ebbr2, I'd guess that neither of you have ever had command of a large aircraft, and therefore never had to face the fact that you shoulder massive responsibility...ALONE...for your decisions, good or bad.
It seems to me now that this thread is dividing into two camps. Those who've been there and done that and learned a lesson the hard way (like me) and the rest, who have yet to learn (or are SLF masquerading as pilots).
Lets cut to the chase.
To any passengers out there reading this who feel that you can act in any way you choose simply because you've bought the ticket....here's a tip.
You might be lucky and get away with it some of the time, but the chances are equally good you're going to meet me, or someone like me, who will not tolerate any bull**** and will disembark you at the first whiff of trouble.
Your call.
Just remember your manners.
