You were at the bar alone chilling and watching some fights happen. As you watch one of the fights someone taps you on the shoulder. You turn around to see a girl that's a bit scared, you look up and a guy is following her. You ask if she knows the man, and she says no. You tell the man to get lost, and the girl hides behind you. The man doesn't take no for an answer and still tries to grab the girl. You tell the man to stop but he still doesn't listen. What will you do?
