In this situation, just by the way he's gone about it he is blowing himself out so you don't need to try and use tactics, just smile and be indifferent, maybe start talking to the barmaid, order a drink or whatever. His money and looks are irrelevant, the fact that he has no group social skills and respect for your conversation automatically puts him at a lower value than you were at. To lower his value more I might be friendly to him and introduce myself hoping he rejects it and comes across even more arrogant.

If he lasts more than a few minutes with her or actually has some game, I'd manoeuvre around, and so only she can hear say "I'm of to the toilet, have fun with your creepy new friend, will be back in a minute" with a smile and some Kino.

The vibe is what you make it, the fact that he threw you off and you believed he'd killed it was what probably killed the vibe.
