While playing over the weekend in an Indian Casino I had something happen to me that has never happened in over 11 years of playing blackjack. I bought in for an odd amount and was given an extra $20 in chips. I've been overpaid before, paid when I lost, paid on a push, but never given more chips than I cashed in for. It really surprised me, especially when the dealer called out changing X and the floor person just yelled back "change it." My first thought was do I say something or do I just act like I didn't notice. Well, of course I chose the latter. Then I'm thinking to myself, how the hell do I account for this in my records. I decided it was the same as an overpayment while playing and just figured it's part of the advantage of being a sharp player. I never heard anything about it from the floor or anyone else. I wonder if surveillance even noticed, probably not.
