To be fair that just seems like a rogue crew member or someone who just got it plain wrong. Contrary to what most believe, crew usually have a conscience and will go about things in the correct manner. Even at my sales conscious airline, doing that would be deemed as a no no in employee circles if not by the airline itself.
