There have been some gals I never met up with because there was so much BS going on, it wasn't meant to be.

However I can think of a couple of gals who I see and really like where there was some crazy stuff that went on before we met and the session went great.

One involved getting the wrong room because the hotel had two towers with the same numbering system in each.  (You guys/gals in Boston know which one I mean.)

I am not an experienced hobbyist and do it mostly overseas where the added freedom of the hobby may makes things different but in my opinion, aside from the blatant good or bad, you never know. One of the best sessions I've ever had was a repeat just days after a so so session. I went back because of how incredibly gorgeous this girl is and that second session turned out to be amazing in terms of personal connection, sex and fun. In life, everything is about timing. My point is that it may not necessarily be the person you have an interaction with, rather the time at which this happens.

It really depends on the girl. Some girls might take some things personally, such as when appointments don't get set up smoothly. Then they might let that affect their performance during the session.
