The San Francisco Fire Department evacuated a restaurant after someone shot off some pepper spray, according to a spokeswoman.
Speaking to NBC Bay Area by phone on Friday morning, spokeswoman Mindy Talmage said she didn't know how the pepper spray was released. A dozen people were in the restaurant, but none wanted to seek treatment, she ssaid.
The incident was reported at 10:21 a.m. at Bistro Boudin, 160 Jefferson St., according to the fire department.
"People were coughing in the Boudin Bakery, so it was evacuated," Talmadge said. Fire crews had responded with a team of haz mat crews, not realizing at first that the hazardous materials were made from a chemical inside chili peppers.
