First the Gum Snaps, Then the New Yorkers Do

A guy pops his gum.

An older woman stands up and yells: Do you think I don't hear you? I've asked several times, who is popping their gum, and everyone looks around, and it was you! You can't do that in a public place! It's a violent sound! Now, will you be able to control yourself, or will I have to run away from you?
