Oh Hilico!!!!!,
Let me put this another way. Operators do not put cabin attendants on anything smaller than HS125's as standard practice unless the client specifically requests one.
I personally will work on ANYTHING that gets airborne, started my career on a private King Air 200 and would say that was the happiest time of my career! I wasn't being flippant just tired after a trip and wanting to get the message over.
