Well, a tip i took from weeds ( the scene with Jessica Jaymes) is do NOT stare at their breasts for too long. They will call you out as a pervert ( when you obviously are) and call security. Consider yourself warned.
I'd probably juts be aware of your surroundings. Treat her like a person and don't draw attention to her profession if you are in a place that may not be as accepting. Ask for an autograph in appropriate places.
The people who wrote the article seems to be assuming that i want to meet a pornstar. I don´t, i can´t think of anything i would want to talk to a pornstar about, and since i´m not twelve years old i wouldn´t want an autoghaph either.
