A San Francisco In-N-Out Burger was temporarily shut down after employees allegedly did not check for customers' vaccine documents, in violation of the city's vaccine requirement. In San Francisco, people have been required since August 20 to show proof that they have been vaccinated against COVID-19 in order to enter some indoor places like restaurants, gyms and bars. The fast-food restaurant located in Fisherman's Wharf was forced to shut down on October 14 but has since reopened with indoor dining remaining unavailable, the company said in a statement to Newsweek.
