MoneyLA. I actually bought someone's hand (but didn't offer the higher payout if I won).
I'm slightly different, as I do enjoy engaging in conversation (especially to those of the fairer sex, great way to break the ice)
First, it depends on how long I've been sitting there. You never know, maybe the person made a mistake and in their rush or routine, they made the improper play even though they knew what the proper play was (I've been known to do this)
Anyways, If I have played for a little while and notice that the person constantly plays incorrectly, I may say something or make a loud enough comment like "Oh, you had 4 to a Royal" or "You didn't want to go after the 4 Aces with a Kicker?" If the person ignores me (hasn't happened yet ), then I'd go back to playing my machine minding my own business. But typically, I get the answer. "What do you mean" Or "How would you play it" or "OH I didn't see that". Then, the next time a "questionable hand" comes up, the person will ask me, "what would you do here". And I would offer my advice and analysis. However, since I don't play VP much, I'm not sure I'm giving her the best advice! . Nevertheless, it breaks the ice and lets conversations flow from there.
Sorry to deviate so much. Anyways, back to the what I originally stated. One woman had a hand where she was dealt for to a royal. K - 10 of clubs and the 9 of spades. I said she had a pretty good drawing hand. She could still get a straight, a flush, a straight flush or a royal. She was undecided between the "guaranteed win" vs. going for it. So I said told her I'd buy her hand. Gave her $20 bucks and fortunately for me, the 9 clubs popped up.
She handed me $250 and it was a great way to break the ice.
