I played at the local casino today and had four mistakes by the dealers. On the first I had a push and the dealer paid me. She was swiping the cards in front of me and I pointed out her error. The second time I didn't say anything and took the money. The third and forth time I had pushes that they tried to take my money and I pointed out the mistake and left after the fourth error. Do you point out an error not in your favor?
