To be honest im suprised this is conjuring up so much debate. This is a minor issue really yet alot of guys seem to make a big deal about it. If you concern yourself too much with getting caught/busted then all you are doing is doubting yourself and building up negative outcomes in your head which can then lead to excuses to inaction.

I like most guys here have been called out before for hitting on a girl, not for using PUA techniques per se. When this happens its about not being phased by it and ploughing on accordingly. Like Kowalski said, its a test, women will test you (and quite rightly to) so deal with it.

And like any test, learn to prepare and you will pass.
