From the sound of it, she does not work for any major US carrier. Back in the good times I knew a very few F/A who pretty much gave the rest of us the reputation of sky sluts. I had the misfortune to get a room connecting to theirs one trip and could not sleep for the racket they made. They had picked up a couple of guys on our JFK-LAX flt and sat in their laps during the movie, made frequent trips to the lav and came out sniffing and then one was not at her door for arrival! I had to run to disarm it so the agent wouldn't get flattened by the slide. Definitely the exception rather than the rule which is why I still remember this incident. Most F/A are much classier than all that.
Every airline is different. Different routes, rates of pay, work rules AND apparently hiring practices.
