Cityfan, with all due respect, I'm not sure how you could have "intimate" knowledge of what happened without being on the scene. That's puzzling.
There is another thing thing.The threat to the Captain's food must have been made within earshot of other flight deck members, if it was made directly. It is hard to believe a senior purser would risk her career by doing that. Regarding the "mutiny", again, if that threat was made directly, would it not have been made within hearing distance of others? Another career limiting move.
