I’m with @
bocastephen in spirit, and I will caution I’m not a lawyer. But, is there any sort of penalty for filing a false report? It could be argued that claiming “incapacitation” is hyperbolic to the extent of falsehood. I wouldn’t want to be tied up in a legal debacle over this.
I don’t want to lose track of the main message here, which is that any FA with this sort of temperament is absolutely unfit to service a flight, because they’d be useless in an emergency.
