I agree with this post. About 30 years ago, I was out "on the road", and ran across Mizerak playing by himself in a poolroom. I walked up to him, introduced myself, laid a hundred on the rail, and asked him to play. This was after he had won several U.S. Open 14.1 tournaments. In noting to him that I had no expectations of being able to win, he asked what I wanted to do. I asked for a 10-ahead set for the hundred, and told him he could just 'put the money in his pocket'! He figured (probably rightly so) that he could win 10 straight, and agreed to the set. My good fortune, combined with some great play on my part, meant that it took him 3 hours to win that $100. The stuff I learned from watching him play, I used on others to win many times that $100 back later. It was, as you described, a "donation for services rendered", and well-spent, imo.
I've also told the story of watching John Barton match up with Buddy, several years ago during a BCA trade show, at the Cue Club on the t.v. table, for some cheap $10 one-hole. Some nit standing next to me, on the rail, made mention of how stupid it was for John to be playing Buddy, when he had no chance to win (something to the effect of "doesn't this guy know who he's playing?"). I replied that he knew exactly who he was playing, and in fact was making an investment in his game! John enjoyed the game tremendously, learned a bunch, and played Buddy about 10 games before Buddy got tired and wanted to quit. Then, in a very class act, summoned a limo to drive Buddy back to his hotel.
