I think your going to see more of this. The FA's I talked to at Eagle are being overworked, underpaid. Most seem to be just burnt out. That includes some pilots too

The Junior mann those girls all the time. I can see how after maybe after a 14 hour duty day, the last thing she wants to hear is some little kid talking while she is trying to give a safety demo. She might have just snapped and that was it.
