A lot of (justified) sarcastic responses. I’ll try to give a productive answer: do you have a political issue you’re interested in, particularly a hot-button issue that’s in the news a lot? Find the organization on your side of that issue. They will host a protest/rally at some point.

You could just be the guy that has a “LOUD NOISES” poster at the protest, or, to put this in meme language, Rob Lowe in the NFL hat.

What are you worried is going to happen? You order the wrong thing and the waiter tells you to leave? Whiteshoe lawyer at the next table sues you because you didn’t order your salad dressing on the side?
