I remember my first game in the nuts poker league before I bought the franchise area, the game was poorly run, ettiquette was non-existent with string betting, mis-placed blinds after players being eliminated, splashing pots, no all-in pot or split pot management, poor equipment and conduct at the tables. After three games I made my way presence felt gradualy, and educated players slowly. Now I run all the games in that venue, the player ettiquette is high, the equipment outstanding and the atmosphere highly enjoyable. I know I am rambling a tad but just an example of how education and showing players and venues that there is a better way can really make leaps and bounds to improve poker for everyone concerned.
In your situation, it should not of happened, but we as professionals, should look to educate these venues for the betterment of poker, once they see the difference, they will grasp TDA rules with open arms.
