The only time I was ever asked to leave a casino involved an exposed Ace.
Female dealer drew to a five card sixteen and drew an Ace. Kept drawing and drew a second Ace. There were two players at the table and we both called her on it and she quickly withdrew the second ace.I was playing third base and the other player was in the second base/shortstop hole. I quickly stood up, moved to first base and threw about $50 of my $80 or so bankroll in the circle, saying last hand win or lose. Dealer now proceeded to try to bury the Ace but I insisted it was my card. The dealer called the pit and after prolonged discussion it was agreed that the ace would be dealt. Amazingly, the other player was 100% in my corner, insisting the card should be put in play. Pit asks me if I had been betting that much every hand and I said no,but I was leaving and wanted to win my money back. Pit tells me he'll only allow a $25 bet( I'd been betting $3-$10 previously), and that this was to be my last hand for the rest of his shift. I agree but try to push another $25 into the circle. He pushs it back and says deal. I get the Ace, followed by a four and dealer pulls a seven. I hit and draw a ten,hit again and draw a three. Dealer shows his ten and I win. Pit tells me to leave and not to return. At the time, it was the largest bet I'd made on a table.
