Thanks bros, your comments eased my mind today that I had maybe overstepped the mark last night, but as you say it was my major sticking point and I was out to address it. Dale's comments also helped me to realise it. It was just a bit 'uncalibrated' (sorry for that
PUA term). But that will come right with time.
I know if I had been really bad, the bouncer would have told me to leave and he didn't. He was on my side. A single bloke surrounded by girls and going for it. He totally understood the situation. Good man.
