At the casino a while ago, I was sitting beside a guy who, like many other ploppy's, stood on 12 against a 2 or 3 every time. I, of course, hit it, and after hitting it about 5 times, this conversation starts:
Him: Why do you hit that, you should be staying you know?
Me: No, I play basic strategy, and it's a hit.
Him: No, I'm pretty sure it's not a hit. Anything over 11 with the dealer showing 6 or under is always a stay.
Me: Hey dealer, what does your basic strategy card say for a 12 against 2 or 3?
Dealer: It says it's a hit, sir.
Him: Well that doesn't make much sense, the math shows that it's a stay.
Me: Actually, there's about a 2% edge for winning if you hit rather than stay.
Him: Well that's hardly any edge, what's the point?
Then I just stopped talking.
