I wasn't going to comment on this incident because I am not familiar with Table Mountain, nor have ever visited. But Dan specifically asked me to read, so I will offer a couple thoughts.
1.) and most important. Call Bob Nersesian, or if you think there is another knowledgeable gambling related attorney (there isn't) then call them and discuss the matter. There is no substitute for sound expert legal advise in these situations. And these casinos are actually counting on you not doing just that. It is part of them thinking they can do as they like.
2.) This is the problem with Indian Casinos. They are basically free to do as they like. They answer to no one in most cases. And it is getting worse. It is why I avoid Indian casinos even though on paper (according to rules posted) they some have pretty good looking blackjack games....that is to say if they aren't cheating.
3.) I have been telling people for a while now, we are now in the midst of a casino industry wide, crackdown on machine player AP's, similar to the crackdown that blackjack card counters faced decades ago. You guys are going to have to re-evaluate how you play and learn to play the cat-and-mouse games just as card counters have been forced to. And that is going to be difficult for machine AP's because is many cases, points, cashback and mailers are part of what makes a play profitable. How do you play unrated? I don't know. But these are a changing times for machine AP's, unfortunately.
