I preface with how many games I have time for. Just went out to pick up food last night. Stopped at a local bar for a quick game nearby. Got on a table and a patron asked if I wanted to play, I said sure how about 20 a game, but I only have time for a couple racks. He says ok let's play for 10. I let him pick the rules and break. He says scratches behind the head string. I win the first game, he says double or nothing, sure. Second game comes down to my 2 balls each I scratch off an unlucky carom. My 9 is left and he had two solids. Takes ball in hand to shoot MY 9 with easy position on the 8. I mentioned that we were playing in the kitchen. He says no, I already scratched in the first game and played from the head string ... ok whatever. He shoots my 9, and leaves straight in on the 8. I say that was my ball. And shoot the 8 for the win.
I collect 20 and he wants to play again. Sorry, got to run. Told him I have an order that's ready... bye-bye
I would make a note not to play your opponent again. I let the other player make the rules but then we both played by them. I didn't let them change the rules as they went along.
