My advice, consider your friendly (or not so friendly) FA to be the equivalent of a municipal motor cop, if you are in his/her sights, all the kvetching in the world about laws and constitutionality wont keep you off the hood of the car face-down in hand-cuffs.
Conversely, if you are polite and compliant, you will have a more pleasant flight. FAs have ways to make things easier for passengers they like.
I always try to be the easiest passenger on the airplane, and as a result, I get excellent friendly service.
