Well I think you would be able to tell a serious buyer from a look-e-loo IMHO, people often betray their true intent with subconscious movements and such. I am not trying to say you did anything wrong but I am pretty sure they could probably tell that you were not a serious buyer, I am sorry if you are offended but that is just the way I see it. Maybe they felt that the way you were asking to see it and from your tone and mannerisms that you were not serious, I don't know I was not there. Speaking of boothbabes I go to E3 every year and they have them everywhere, using super hot chicks to get geeks into your booth to talk about video games usually works.
