wow, dude, seriously I think I don't think I could have made a nightmare go that bad
Here are the key places you went wrong:
1) You performed on private property
2) You performed for people while they ate
3) You tried to please this girl when she clearly wasn't interested
4) You obeyed the crowd and kept performing (you need to leave them wanting more)
5) You let the other tables join in on the "fun" (again you should have quite)
6) You didn't use any lines to stop any hecklers (go to the "outs and one-liners" section)
7) You left, then immediately started up again somewhere else

You kept performing for the friend even though he was getting cocky and you knew he knew what you where doing
9) You did the monte for money (this is probably your worst mistake, seeing as this is ILLEGAL! And you very well could be arrested...
I really think you bombed that particular day. The only "score" that I could see is that you impressed the sloppy eaters...
