Sean Penn yells at fan in San Francisco hotel bar

Sean Penn screamed at a fan in a San Francisco hotel bar on Tuesday night.

Sean Penn – who served 33 days in 1987 for assaulting a photographer, and allegedly beat up two shutterbugs in 2009 – was taken by surprise by a fan who apparently tried to take his picture with a cell phone at the St. Regis hotel bar in San Francisco.

“Do we look like f***ing zoo animals?” Sean Penn screamed as he approached the man, who TMZ reports had attended the same conference the actor had been at that day.

According to the gossip website’s video footage of the incident, Sean Penn then grabbed the man’s phone and chucked it on the ground, yelling: “I’ll make you eat the phone … get the f*** out of here!”

Sean Penn later suggested to someone who worked for the hotel: “You should do something about that.”
