Did I really prove a point?

I recently joined Chisolm's APA League on Sunday nights. I only agreed to play so long as I was never asked to throw a game or play below my handicap. The more I've been playing, the more I've been appreciating my teammates. Their eagerness to learn more and more about this game is what has kept me playing with this team. Anyway! Here's the point... Last week, during my first match, my opponent's teammate made some rude comments to my teammates about my game. I had not warmed up and admittedly was not playing my best. Although I stayed ahead of my opponent and eventually beat him, his teammate still found it necessary to tell my teammates that I wasn't playing up to my handicap and basically that I was overranked. Well, after league I approached this guy for a game. I said, "What do you want to play for?" He only had $7 to his name so we played one game for $5 and one game for $2. Not only was he not a good player (and didn't realize it) but he had stepped right out of my book, as though it were his bible. He didn't just get down on his shot before the cue ball stopped moving, it was going mach speed when he would get down and would never stop anywhere near where he was positioned. While I was down on a shot, he even tried to ask me where I was from. I said, "I'll answer any of your questions after this game." Anyway, I took his only $7 and he claims that he'd have more money to lose this week. After we played, he began telling me about all these other bars I could go to for good gambling action and where I could find people to gamble with. To all this I responded, "I don't even like to gamble. I only played you to prove a point. I heard what you said about me and I didn't appreciate it." He denied that he was trying to "talk sh*t" and claimed that he was only trying to boost his teammate's confidence (even though the teammate wasn't around when he made the comments). He completely tried to back-pedal his way out of it. The bottom line is: I am a far better player than this guy and will beat him 99.999% of the time that we match up. He is a decent ball-maker and that's about it. I would never gamble with someone just to take their money. It's not about the money. It was about the principle. However, I still wonder if continuously taking his money will ever really prove a point... On a side note: Personally, I am a tournament player. I train to compete in a controlled, respectful environment. I am courteous to my opponent and expect the same in return. I would not object to scheduling a gambling match where both opponents know when and where it will happen and I am playing a race for a certain amount. But, I do not agree with spending 13 hours in a pool hall, only to break even. Is this right or wrong? It doesn't matter. It's my choice. I choose to be a tournament player.
