Which property? For some of their properties they have a lot bigger fish to fry, like this guy who bets $150,000 in one hand, or the Department Store owner who counts, or the Asians who throw $2 million in an attempt to win $25 million. So some guy like me betting $25 or $50 is not even a blip, unless of course its an extremely slow day, or the pit calls the eye with a heads up. The way it was explained to me, they may catch you "casing" the game at $25 or $50 with the intention of coming back tomorrow and withdrawing $30 or $40 thousand. So they err on the side of caution and back you off when they observe you counting even if you seem like a penny ante player.
