Do you have a good suit, shirt, tie and nice polished shoes.
If so try one of the nicer hotel bars. Be careful not to ******* to much.
Have a smile on your face.
Stand alone at the bar.
Basically be approachable.
Remember breath mints and clean teeth go a long way to you being picked up.
A good hand shake is important. Firm but not hard.
Make eye contact with each of them. She maybe smoking hot but ignoring him is a fem (fuck ending move)
Let him talk and he will talk her into it. Let her talk to insure you get action.
