When a casino opens it only becomes a real "candy store" when it is located somewhere that has no other casinos for them to draw EXPERIENCED players from.
Under those circumstances, the rate of dealer errors is very high.
The dealers are inexperienced, happy to be working, and eager to please.
If you tell them to insert the cut card near the bottom they are likely to comply.
Getting paid for a BJ on split Aces or Tens may happen.
Resplitting Aces you may experience even though the casino does not offer it.
The advantage is that the floor will have its hands so full watching the dealers that they have no time to watch YOU.
These things will not happen in Las Vegas though, because the new hires are not inexperienced.
The one time that I was there at the opening of a rural "Candy Store", I sat next to a fellow who was a floorperson at a casino 200 miles distant.
He counted using "Uston Advanced Point Count" and I side-counted Aces and kept an Insurance Count.
Almost needless to say, we both did very well playing off of a joint bankroll.
The biggest advantage is that the floor will have its hands so full watching the dealers that they have no time to watch YOU.
As I said above, this will not be relevant to the opening of "ARIA"
