I've only ran across one delta captain that was rude. I am assuming he was an IOE captain and the FO for that flight was brand new. He was very disrespectful to the FO.

Riding with me, FO at ASA, it has been all good except one AA pilot. Can't remember if he was an FO or captain. After push back he began eating a footlong sandwich which was right in my face, RJ-200. While taxing he taps me on the shoulder and ask if I could hold his bag of chips for a moment.

Maybe if I had the chance to eat that day between my 6 legs it wouldn't have made me so irritated.
