The vast majority of F/As are exceptionally professional and excellent. As in many similar industries they have to deal with their fair share of awkward, argumentative and drunk passengers. There are however some overzealous types who seem to enjoy unnecessarily flexing their muscles and invite confrontation where none is needed. If a passenger on the receiving end of such then responds (in a calm and polite manner) by making a valid point, these unprofessional F/As will invent a trumped up charge and threaten such pax with the Captain or the police on arrival. I have been flying regularly more than 60 years and, to be fair, only witnessed this a few times, once with myself on the receiving end. (it was sorted out quite amicably with the Senior Purser). All of these (few) incidents occurred in the past 20 years or so. Sign of the times?
