The only San Francisco location of wildly popular California-based fast food chain In-N-Out Burger was temporarily shut down and remains closed for indoor dining after the SF Department of Public Health found the restaurant was not properly enforcing the city’s vaccination mandate for indoor dining, KRON4 reported first. The city shut down the restaurant at 333 Jefferson Street on Thursday, October 14, after learning staff weren’t checking diners’ proof of vaccination or preventing customers without proof of vaccination from entering.

The restaurant has since resumed takeout and outdoor dining, but the company seems to be digging its heels on the vaccination mandate: In a statement provided to Eater SF, In-N-Out Chief Legal & Business Officer Arnie Wensinger says the company believes requiring its staff to enforce a vaccination mandate constitutes government “overreach” and is refusing to do so. “We fiercely disagree with any government dictate that forces a private company to discriminate against customers who choose to patronize their business,” Wensinger’s statement reads. “This is clear governmental overreach and is intrusive, improper, and offensive.”
