Yes a few. Like most, I don't mind losing if its been a good, evenly matched game. I play one guy fairly regularly over the best of 3 with a tiebreaker in the deciding 3rd and he pipped me 7-5 in the deciding tiebreak. But it was a great game and I don't think either of us minded losing.
But then if I just play badly and lose a match rather than getting beaten, it frustrates the hell out of me and I have to get out there again to finish my weekend's tennis on a high.
