Seeing the thread about mistakes in your favor makes me think of one of my most memorable experiences in the opposite category. A mistake made in the house's favor. This was in the Mirage, probably around 2005. I used to go there mid morning to play the $25 double deck, DAS, with of course 3:2 BJ, on the blackjack tables. I'd get a comp breakfast for 2 ticket after just over 90 minutes of play. I had my least favorite hand, 88 against a dealers face card. Of course I split them (a defensive split, pretty much by the book). I don't know what I had on the first hand, it either busted or lost, but I had a 19 on the second hand. The dealer had 18. He picked up all the chips on my side of the table, as nearly everyone had lost. $25 a hand minimum was a little over my comfort level back then, and I was trying to disguise my card counting, so I was probably not very relaxed while playing. As such, I wasn't 100% sure (probably 85%) that he had made a mistake on my winning hand. As the dealer quickly started dealing the next hand, I put my hand up. "Wait! I had a 19 on that hand, and I think you didn't pay me". His words, and more his demeanor, tone, and attitude still ring in my head to his day. "If you won, I paid you!". I feared looking pretty stupid if I was wrong, but I didn't back down. "No, I am pretty sure you didn't pay me.". Again, a stern reply, "If you won, I paid you". I said, "everyone makes mistakes once in a while, couldn't you have made one there?" "If you won. I paid you!", again, said in a condescending, confrontational way. No other words came out of his mouth. I was calm and polite in my manner with him, and a little bit unsure. Three of the others at the table got up and left, probably annoyed at the situation, but not one person spoke up, either for me or against me. Finally the pit boss came over. I explained the situation. He said he would call upstairs to have them play back the tape. I was dreading how I would feel if I was wrong. The game went on while they reviewed things upstairs. About 5-10 minutes later, the pit boss approached the dealer and told him to pay me, he had made a mistake and not paid me on my winning hand, just like I had said. Vindication! I looked at the dealer, and he wouldn't make eye contact. "No apology?", I asked. He then looked up and gave me a look that could have killed. I actually feared a bit for my safety, and left the table shortly after that. I made a bit of a comment to the pit boss away from the table, but thinking back, I should have done more, and described in detail this situation. Hopefully this mistake went on his record at least, and if it was a pattern, maybe he would have been guided to a new career. It certainly was one, if not the most, negative casino moments that I can remember.
