The last thing you want to do is air your dirty laundry for everybody else to hear. If your partner persists, do your best to shut it down with a warning look. Should he still not get the message, calmly suggest you resolve the issue later. If that doesn't work, take it outside. While you can't control somebody else's actions, you can control your own. And by now, we all know it takes two to make a thing go right...and wrong. Another way to avoid public displays of aggression is to avoid topics and situations that get you or your partner hot under the collar. You know your significant other well enough to know what pushes his or her buttons, so just don't. When you are out and about, strive to be on your best behavior for the sake of your relationship...and your loved ones.
