Poker Etiquette: Where is it?

[soh538]

Just came back from playing poker this weekend at the Borgata, playing in a few tourney's and some 6/12 games. I noticed as more and more people start to play poker, there seems less straight foward play. There seems to be more grandstanding, showing your opponent a card at the river that is not the top pair, then slow rolling the best hand. Another problem is, asking your opponent at the river if they have a straight, when you know you have a fullboat. The ultimate for me is telling your opponent that you have him beat on the flop, isn't it your job to make money with poker, let him call with the worse hand, and let him pay you off, don't talk your hand. Any good dealer would stop these tactics,but there are so many new dealers and they have no clue about etiquette. What should we do as players to stop this from continuing as our hobby is booming? Thanks for listening.
