Own The Audience
Get the audience involved:
When you enforce a popular rule, you re-engage everyone who supports that rule. You restore your power and earn the audience’s respect. So, don’t hesitate to cut off a blowhard, silence the guy on his cell phone, and interrupt the table having a private but distracting conversation. As long as you are polite and direct, you’ll be a hero.
