FA's that chime up "just to chat" in cruise. And by "just to chat" I mean "lay out the entire family history, including the political, educational, and socioeconomic reasonings behind why they became a flight attendant". Light banter for a couple minutes...no problem...but if you've been on the phone for more than 10 minutes...there's an issue.

Explaining to a captain that you double-deadheaded to get there and this is the only leg you're actually in the cockpit for because you're on reserve and they say "Ok, I'll take this one".

CA's that get thier panties in a bunch when you try to help out a lil' bit or make a suggestion...then get just as upset when you don't say a word because they flipped out the last time. That's always fun.
