I was playing Pai-Gow poker at a casino with my parents and some friends. The game has side bets, which pay out if you get a good hand, independently of whether you win or lose, and (inversely) proportionate to the probability of the hand. By the numbers they're terrible bets (while Pai-Gow has the, I think, third-lowest house edge, after craps and blackjack), so my friend and I don't bet them, but my parents do. My friend got a great hand, full house maybe, and my dad said, "bet you wish you'd made the side bet," and we both said, "no, we don't."
