I usually open with "Hi". At the bar last week, I went up to 3 girls, just said "Hi" and put out my hand. We got to know each other, I remembered their names correctly (they were impressed). Sat down with all 3, and we maybe spoke for about 20 minutes... 2 were definitely attractive, the other was meh. I ended the conversation rather abruptly and went to meet this girl I had planned to meet. (ended up scoring with her that night)

My question is, what is a way to ask one for a number when the other 2 are there? Should I just ask? I try to be as suave and discreet as possible. It's just who I am.

Whats your favourite method to isolate? Should I just turn to one and ask for her number? I do not want to make the other 2 jealous/uncomfortable.
