Restaurants in Contra Costa County that refuse to check customers for proof of vaccination against COVID-19 soon may discover that health enforcement inspectors won’t be playing nice with them anymore.

The Board of Supervisors made it clear Tuesday that restaurants should be fined if they don’t follow the county’s mandate that eateries, gyms and bars cannot serve people inside who aren’t inoculated.
