Bar Cheating

I was shooting pool last night and the guy who played just before us sunk a ball that he obviously wasn't shooting at. He played it off like it had been his shot all along, and he kept playing. No one said anything. I considered it, but I assumed he'd lose. Then he won and I had to play him. It was too late to say anything, plus I assumed I'd beat him. I scratched and sunk the 8 ball on my first shot automatically losing the game. It was pathetic, but not quite as pathetic as cheating at bar pool.
