I would love to add to this a bit more Lou, as I was in the middle of Eric and John for this argument, and it was actually me who went over and helped them separate.
These two obviously had some bad blood between them already.
It started when I said to the guy who Eric was shooting with "I can't wait to see this match". Eric heard me and replied to me (and towards John) "it's going to be an old fashioned goat roping" John replied "yeah but it won't be the person you think getting roped". THEN John started asking Eric to play a race for a thousand before your match. John did state that challenge multiple times, and finally Eric replied, "what I would like to do John is knock your teeth out". John said "oh, now you want to beat me up? ". Eric said "yeah I'd like to" and John said "yeah, come on" and Eric grabbed a pool ball from his table and walked over to John. Eric took off his glasses. John picked up a pool ball as well. They stood there for a few seconds nose to nose, and all I could think was that I didn't want anything to stop this match from happening! I saw my hour+ drive and hope for a promised side bet with JB (which he bailed on) going by the wayside. I walked up to both of them and said "Come on guys. We have a big match about to happen. Don't let it get ruined". And that was enough. They separated and Eric walked back to his table, but as he walked away he threw the pool ball over his shoulder onto Johns table.
One can only hope that they settle their issues as nicely as the two of you have. On the pool table.
