He was like, 'In my town one day, I was at a restaurant or a bar and there was this guy, and he'd been drinking heavily for like a week," Nasser said. "'And this guy just came at me with a knife, like, for no reason."
This actually happened to me one day in San Francisco although my assailant was armed with a fork, not a knife. A waitress intervened and I went on my way. My experience tells me that nothing is predictable in San Francisco.
