Popular California burger chain In-N-Out is refusing to comply with San Francisco's mandate that restaurants check vaccine cards before allowing customers to dine indoors — a move that resulted in a temporary shutdown of the city's only location.

"We refuse to become the vaccination police for any government," Arnie Wensinger, the company's chief legal and business officer, said in a statement shared with The Washington Post. "It is unreasonable, invasive, and unsafe to force our restaurant Associates to segregate Customers into those who may be served and those who may not, whether based on the documentation they carry, or any other reason."
