Unsurprising. A disturbing number of inflight staff wig out during irregularities. NTSB accounts of non-fatal incidents are rife with stories of FAs panicking, freezing up, fainting, weeping, screaming, etc. at exactly the point they are supposed to be earning their keep. I hope and assume this woman has been permanently grounded.
I take all that self-righteous talk about how "we're here primarily for your safety" with a big grain of salt, as statistics show a fair number of FAs make things worse, not better, and I would never count on inflight staff to "save me" in an emergency. On each and every flight I make my own plans.
