Same thing..
I was playing recently and had the same thing happen to me. I was at the casino playing Bj and another counter from this message board was playing on the same table. The count got bad and I said I wanted to sit out a hand or two. Maybe change the rotation of the cards. When I asked to get back in, the dealer said no. The dealer called the Pc over and double checked. The other players didn't care, but the Pc stood firm and said no. O'well, it saved me some money! By the way, it was DD.
