Patronis appealed to In-N-Out CEO Lunsi Snyder to move to the state, arguing that Florida has a superior business climate—noting the state has no personal income tax, low corporate taxes, and no mandates.

"I'm writing you today not only as Florida's Chief Financial Officer, but as a small business owner who grew up in a family-owned restaurant and worked there for more than 30 years," his letter reads.

"I know how hard it is to turn a profit and make payroll on a good day, let alone when your own government is working to crush your business with absurd mandates. Once I heard the news of your shutdown for refusing to act as 'vaccine police,' I knew I had to reach out immediately."

It came as health officials in Contra Costa County, Calfornia, shut down another In-N-Out Burger location for allowing indoor dining without checking customers for proof of vaccination, coming after a location was closed in nearby San Francisco for a similar reason.

Contra Costa County District 1 Supervisor John Gioia claimed that In-N-Out's staff in Pleasant Hill "have just flouted the law."

"It was other residents who complained about them," he told ABC7. "That is why the health department followed up and issued fines."
