I did have something like that happen to me too. I was playing a military championship in Mannheim, Germany, where ALL men in the field had to spot ALL women in the field 2 games in a race to 5 in 9 ball.
I played a girl who didn't pay bad, and won 2 games on me before I really had a chance (slopped in some balls). I then turned up the heat and won 5 straight games. I went to shake her hand, and she insisted the score was 4-4. There were no scorekeeping beads, and in such a short race, I hadn't seen the need to put quarters under the rail to keep track.
I explained to her exactly how I won each game, and where I shot key balls, and she said "I don't know about that, but the score is 4-4." Her male friend backed her up, and my wife didn't love me enough to watch my matches all the way through, even though she was at this tournament..

I got so royally pizzed at what the lady was doing, I ended up losing the next game and the match.
I then played like a man posessed, she got eliminated by someone else, and I played the reigning US Army Europe Women's Champ in the finals. Had to beat her two races in a row. Final score: 5-2, 5-3 me. This included her handicap. The only game she got was when I payed her safe, she tried to bank the 1, hit it so bad she bank combo'ed the 9.
As for the other chick.. Well karma is a #$%^&, ain't it?
