It's not just women. You are just as shocked when the good looking jock type at the front of the booth with the expensive haircut knows anything about the product other than the price and his commission. It's all a pattern recognition excercise. At an American or Japanese company, attractive young women on the stand are statistically likely to be at worst hired booth babes and at best someone from marketing. In a european company they are likely to have PhDs in engineering. Similarly the guys in the fancy suits with the $100 haircuts are going to be sales. What you are looking for is the scruffy guy at the back climbing behind the PCs checking the cables. If he is in a black T-shirt with a roll of duct tape he works for the show organizers. If he is in a company T-shirt with glasses he is the one techy they sent along.
