I highly doubt there is someone sitting at a computer in the pit (or even upstairs) that is googling everyone from their Id.
But I also feel like Druff isn't providing as much information as he can. And that is fine. He may have reasons to.
Personally I would like to know more about the "independent casino" comment. Are we talking Mohegan Sun (virgin), or Palms, T.I. or M resort that have no other sister type properties here in Vegas, or are we talking truly independent like Strat, F Bleu? Oh wait, is Strat associated with somebody like Az Charlie? I forget. How about Sahara? Anyway, would need to know Druff's definition of independent.
But on the other hand, no casino that relies heavily on database info is really independent.
I would also ask, any backoffs or heat anywhere recently? Or even in last year or two? If you play Vegas regularly, you will see pit folks that you recognize from other properties. They do move around, get laid off, take new jobs ect. especially when a new casino opens. I know a player that was backed off a place he thought he was good at only to discover someone in the pit that he had previously had a nasty backoff with at another casino. So THAT happens.
But to me, taking Druff at his word (and I do) and hoping he isn't leaving a major part of the story out, The thing that stands out most to me, is CSMs at every table except this one, where there was seemingly a good playable game. That is a bit of a red flag to me.
