About two dozen customers barricaded themselves inside of Nueve restaurant when authorities told them to "stay far away from YouTube," around 1 p.m., bartender Carlos Gutierrez said.
"Is this really happening?" Gutierrez said he wondered about the reports of an active shooter at the company headquarters in San Bruno. "Or is it a false alarm?"
On the TV, a woman with blood on her was later interviewed, he said, confirming to him that this was the real thing.
