Monica Fukuhara was a college student working at a restaurant when it happened to her. As she was saying goodbye to a customer, he grabbed her chest, she said.

"I didn't tell people close to me what happened, certainly not my family," recalled Fukuhara, now 26. She remembers being left with a feeling of helplessness and anger, which soon turned into shame.
