I know this girl, she is the marketing manager and is actually a really decent person both professionally and personally. She would have no idea of the facts surrounding the situation and I guess she is just doing her best to be polite and understanding on a very busy stand....Her responsibility is the advertising, the stand, the
pr etc and she would (I am assuming) know nothing or at least very little about what you are trying to talk to her about.
I understand your aim with the video but I don't think it achieves it as its the wrong person to speak to and she is just doing her best. I feel sorry for her more than anything as this is really not a very nice experience for her to have this on Youtube and mailed out to affiliates and operators when she is the wrong person to speak to and she is just doing her best to answer your questions and be polite.
