you're approaching it all wrong! thats like saying "omg you're so beautiful can i buy you a drink?"!!!
look at it from their perspective ok...
you're sitting there with your friend at a table... having a really good conversation... and then this fat bush pig looking chick walks over and says "hey i really like you guys, can i sit here with you two with an awkward vibe between us all and we can talk about the usual stuff like what you 2 do for jobs and what your favourite colour is?" think about it... what would you do in this situation?
i'd be thinking to myself "who the fuck is this chick and why the fuck does she want to sit down with me? she must be of such low value that she wants to hang around high value people..."
thats what i'd be thinking lol... so you need to be an attraction... you have to make them want you to stay rather then leave... change your approach and remember to throw in false time constraints so they feel more comfortable and your game will improve
