You and me both. Once in awhile I’ll come across individuals who do things such as this and I usually will politely address them.I would have calmly dressed down the jump pilot, preferably in front of a crowd. Indeed I would have been unable to leave without doing so. He created a very clear safety hazard. If I just let it go he could do the same thing with less desirable results, and some of that blame would be on me for not doing anything when I should have. I think a little reminder that he was depending on his ticket for his livelihood and his future and had quite a lot to loose with his unsafe behavior.
I put myself in their shoes. If I do something that was incorrect, I want to be told so I am made aware of my wrong doing.
