Was walking by a bank of $1 DDB at my local and see a guy with dealt 4AAAA but he's only got the 4 aces held and he's about to hit the draw button. I said, "hold the 4!!". He stops, but he's completely confused as to why I'm telling him to hold the 4. I show him the differences on the paytable. He's still not completely following but he holds the 4, asks if it's ok to draw now. I said yes, he does. Then he says, I've never seen anything like that before. Can you imagine? Playing DDB with no concept of kickers!!
