Getting Handsy

I was on a midnight flight from California to Israel when a woman woke me up to inform me that the man sitting next to her was getting himself off with his hands. I escorted her back to her seat and saw it for myself. Even though I asked him to stop, he continued and finished into the blanket. The worst part is that he was sitting right next to his mom, who we woke up to tell her. She scolded him and apologized to us.
