Imagine you’re watching the following story unfold. After you hear what happened, I’d like you to consider what you would have done (if anything) had you been there.

You’re at one of those restaurants known for heckling diners, supposedly all in good fun. At a table nearby sit a mom, dad, their two children — ages five and seven — and their 17-year-old niece. From the start, Anna, the 17-year-old, is targeted for ridicule. Her waiter, nicknamed Buttercup, first teases her about the small “star” tattoo on her shoulder. Then he brings out a paper hat with the label “Puberty Sucks” and puts it on her head.
