How is it possible to get mugged by a single man? Even though men are physically stronger, it's still extremely hard to hold someone still for any period of time. Also, if you're not holding your hands on your wallet, and not willing to stop clenching it doesn't seem like it would be possible for someone to steal from you. I just can't wrap my head around how a dude seeing someone on the street in the middle of the night could possibly end up in a robbery.

From threat of violence to actual violence. He has a knife or a gun. You are getting punched repeatedly in the face or getting choked. Can you not imagine a scenario were someone is getting overpowered?
