You do things like this EVERY DAY without thinking about it.
Every day, you walk past charity workers, homeless people, salesmen, and people handing out flyers and completely ignore them, lie to them by saying you're busy, and generally don't give them a chance to talk to you or show them the tiniest ounce of respect.
Why?
Because you assume they're just trying to take value from you, and thus you shut yourself off to the possibility of interaction from the very beginning, because if you do engage them, and they turn out to be really nice and friendly, then you'll feel bad if you don't give them something.
Girls in a club dancing around having fun are gonna get approached by TONS of guys, mostly drunk, with shit game. They can't possibly talk to every single one of them, otherwise they'll never have a moment to spend with their friends just having a drink, talking and dancing. So, when a guy comes over, they just look immediately at a few aspects, and decide the probability of this guy being a chode, and then just shut you out before you can even say anything.
If you are getting blanket rejections like this, it's likely you're subcommunicating that you're nervous, or that you want to take something from them, or that you expect the interaction to not go well. You can help yourself by working on body language and posture, getting into a good state and having fun with your friends first, and opening sets around you with proximity first.

http://www.yourcharismacoach.com/ when going into a new interaction, you can actually believe that it'll be good 100% of the time. How? Well, instead of thinking "she's either gonna like me, or I'll get rejected," think - "either she'll like me and it'll go well, or it'll be a funny story!" I now go into outrageously difficult sets, precisely because I don't give a shit anymore about rejection. In fact, sometimes I go in purely for the lulz of having a hilarous blowout and being able to tell a funny story about it!
Case in point - I was in a chemist buying condoms and lube about a month back, and I thought to myself "this could be funny." So I turned to the girl in the queue in front of me, and was like "hey, I know this is a bit random, but I'm actually gonna be trying these out later [holding the condoms and lube in either hand] and I was thinking maybe you'd like to join me?

" Needless to say, she was stunned and said NO. So, I turned around and said basically the same thing to the girl behind me (also really cute!) and she said no too. Then I turned back around to the first girl and was like "ok, forget about these, how about just a coffee?" and she said no again. What was really amusing was that since it was in the queue, she couldn't just leave, making the situation 100 times more awkward! I love creating awkward situations and just revelling in them, that's the basis of great humour!
So, a couple of weeks ago we were out teaching a bootcamp and filming, when a girl was passing by us, and she stumbled and tripped. Some of chuckled a bit, and I was like, "actually she's pretty hot!" So I ran over and said hi. "Oh my god - I know you!" she said. "ORLY?"
"Yeah, you're that guy from the chemist a few weeks ago!"
We joked and laughed about that, and I got her number and set up a date!
So even when I went in and got PURPOSELY blown out for the fuck of it, I still managed to see her again and get her number. Even in the worst possible case, it was a funny story and I got a date out of it.
Thinking like this, will actually mean that your "rejection" rate goes way down, and will only keep reinforcing that you only get good reactions from women because you're always having a fun time!
