Pee before you leave, never a bad idea to stop in at the pub nearby if you had a long commute and pee again.

With regards to building rapport, try your best to ask some direct questions, nothing too personal and see how the conversation flows. Some girls don't want to talk, others won't shutup, it really depends on the WL. Sometimes you get a great connection other times its like talking to a robot.

Can I address this issue you have with your self image too? Soy as fuck means what? You may have had limited experience or negative experiences in the past. But so what. You're on a journey to improve yourself and gain experience. Every experience with women both in and out of shops will build confidence and capability over time. Your AR above showed that you learned a lot about the punting game and yourself in just one session. Why go into this with a negative expectation of how you will perform, what will happen or will this be like sometime in your past. Fuck that, be in the moment and enjoy yourself.
