Another interesting aspect of the situation is where the regular CC pay no attention to the cabin Chief...because of his/her nationality....or any other reason.
Recall years ago enroute DHA-RUH and scheduled to CDG, the cabin Chief (from Morocco, and very competent) complained that two CC would not follow her instructions.
Had 'em offloaded at RUH and replaced....they were summarily dismissed a few days later.
Not wise to challange the Chief.
