It's all very simple, folks.
Airlines have rules and regulations, the respective regulatory authority have the same, and it is expected that FD crew follow these rules and regulations to the best of their ability.
Airline flying is a highly regulated endevour for a variety of very good reasons, and folks who constantly flount those rules and regulations are shown the door....and told to not let it smack 'em on the behind on the way out.
End of story....case closed.
