The first week I started dealing blackjack I was on a double deck table which was completely full. There was a pretty woman playing on 3rd base and she was laughing and talking to her friends who were next to her. I dealt her 2 cards and she glanced at them and made the hitting motion. I had flipped the card half-way over when she jumped up and started waving her hands around screaming, “No! I made a mistake. Don’t!” By the time she had finished that sentence I had already given her the card and it was an ace. She flipped over her two cards to show a 20. She had hit a 20 and got an ace for 21. In the 5 years I’ve dealt blackjack I’ve never seen that happen again.
