Not with that attitude you wouldn't. Unless you mean hookers.
People are very good at picking up on others' signals, how they carry themselves and interact with others speaks volumes about the probable character, confidence, attitude and "status" of that person. You'd be surprised what you tell people about yourself in social situations without realising. It's amazing how subtle and yet profound some of those signals can be. I think women tend to respond to those signals more acutely than guys.
Just go to a bar one day and watch others, try to pick out the winners and losers (for want of better phrases) and notice how diverse the people who fall into those categories are. Then consider what those people you've pigeonholed this way did to deserve it. See if you can spot different people making the same mistakes or demonstrating the same positive attributes in their characters (not their appearance). Then learn from it. You know, you do choose the character you project to the world, whether you realise it or not. And it's fluid. Social interaction is a skill my friend, and you can learn it if you want to.
