One could also say that she allowed the PR reps to make her feel that way by not speaking up. "I better play it for you" wasn't the first thing the guy said when he saw her. Clearly he had made some assumptions based on her gender, and possibly some previous experiences. But there was a lead up to that statement, where apparently she sat there silently ignoring his questions, looking puzzled. This confirmed his expectations that she had no idea what she was doing.
People are going to make judgements based on what they think they know. They do it all the time and sometimes it is a completely subconscious process. Sometimes it is deliberate. Sometimes it is a result of a lifetime of conditioning. It happens with gender, height, skin colour, attire, and pretty much anything else that you can quickly identify by looking at a person. If someone is judging you incorrectly, help them out and say so. It might be nothing more than an honest mistake.
