I guess the wgs have great photographic memories so they can chase you down after you become famous, rich, and are written up in all the local gossip rags and present you with your love child that came about from a defective condom.
Just kidding, I think having great memory is to serve three purposes. 1) a form of protection. Remembering the punter who abused her, was too rough, too kinky, or stole money so she can refuse entry at the walkups or turn down punter at a sauna/karaoke.
2) to enhance the experience for the good, nice punter on 2nd visit and a corollary to this to speed up the session by remembering which position got the punter to shoot the fastest.
3) when she is on her day-off, to recognize and screen out all those perving punters as she looks for a nice bf/husband. I would think even wgs want to find nice guys too, not those savvy, pervy punters
