My sister has a friend that has a booth at DEFCON, the long running computer hacker/security convention. For some years he hired "promotional models." He also had friends work the booth for part of the time, including my middle-aged sister. What his friends had in common is a lot of knowledge about the products sold. They did far better than the models at getting people to stop by the booth and buy his products. He dropped the eye candy

Sex doesn't necessarily sell. If they claim it does I want to see the data. Maybe the booth babes attract some guys to come by and chat them up, but do they really help sales or is it an assumption that they do?
