Reminds me of me. Just remember to leave the left side of your brain (i.e., speech center) outside of the equation when you are ready to shoot. Don't let them shark you into talking. Just smile and keep chalking your stick until your opponent gets the message that you are not going to shoot until the crap stops. Best to wait forever and let your opponent speak up and tell the offender that the game will not proceed until the crap stops.
Beyond that. Get to know the bartender. Play the music that they like and ask them what's up with the jerks. Even better if the owner or bouncer (if any) is present, get to know them.
Also, who's running the tournament? Talk to them and be nice. If they can't or don't want to control the situation, screw them since they are complicit.
If there are vidio cameras, hope they hit you again and act like you are near death and then call the cops. No bar that I know of wants any police reports. And, any owner that condones this kind of behavior deserves whatever he gets. Hell, set the SOBs up for a trip to the hoosegow and a lawsuit.
Otherwise, as someone else said it's a bar get used to it and don't let it bother you.
