Re: competitors amogs etc
Demonstrating higher value is what needs to happen. If someone comes in competing you can win by being in control. If you got a good opening in and he comes in as a CB then just excuse yourself to another place or even introduce him. If you try to qualify when another man comes in in general you lose, by qualifying you automatically show you feel threatened.
If you introduce him you are controlling the frame and showing you are in control.
Also if you have to walk away after you introduce him that works too just be sure you keep being social with others if your time is valuable to others after a good introduction she will seek your attention.
