Guys, this works great. I've been doing this for awhile and not only (as you guys say) do you know that she is interested when she contacts you, but there are so many fun ways to tweak the interactions. One thing I have found works like a charm is this:
In the beginning of the evening me and my buddies will go to a bar have a drink or two, and then go to the next one. barhopping. Just getting a feel for which places will be hot this evening and enjoying meeting new people.
When we leave some place, I'll get eye contact with a girl I haven't talked to in the bar, then just walk up to her, ignoring her friends if she is in a set, giving her my hand and going "Hey, I'm, Does, what's your name" she then says her name I give her a compliment and my number, and tell her I have to go, but that she can text me if she is still partying later and then we'll hook up and go dancing or clubbing or something.
When we settle down somewhere, I've usually giving out my number to around five girls, usually three text me later. Now this is gives me a lot of fun options.
1. I can sarge away, and just not answer them if everything is going great.
2. I can pick which one I'd rather see, and not answer the others
3. the next day, I can text those I didn't answer the night before, and say something along the lines of "sorry I didn't answer yesterday, my friend got a little too drunk and I had to get him home, hope you had fun anyway

"
Every girl I know have been in this situation, their friend is drunk and they have to babysit her, they relate to this. When she answers (and she will) you can just start gaming her via text, then hit her up the next time you go out.
I actually settled down for around 6 months with a girl I did this to, and she said that she was just sitting there looking at me leaving the bar and thinking "but, but. He said was beautiful, why is he leaving??" and wanting to text me right away, but ended up waiting for two hours so she wouldn't seem needy. hahaha
