So a pax knows better than trained cabin or flight crew now?! I know I certainly dont and I've heard enough safety briefings etc. Stated example was someone positioning in uniform and presumably with a company ID badge with which to identity themselves to the CC. NOT therefore your average pax as they HAVE been formally trained and assessed...
I certainly know who I'd prefer to have sitting next to the exit if there was an emergency and it sure as hell isn't someone with a gold FF card...
