I had some fun with the 3 card poker last time I was in Vegas. The payouts were much better than at the multi-deck blackjack table, where I sat down and lost $30 in five minutes.
I got up from the muti-deck blackjack table and found a single deck table where I doubled my left-over $.
What had pissed me off with the pairs bet on the 3 card poker table, was whenever I didn't bet it, a strait or 3 of a kind would show in my hand.

Seems like that happens more times than not.
But, when I was at a $10 3 card poker table a year ago with $30 left over, I caught the Strait Flush on my $20 including the $10 on the pairs button bet.
I played my winnings down to $350 after a dealer change and got out with the cash.
