Contra Costa County has put the customers of nearly 4,000 restaurants in charge of reporting which ones are breaking its COVID-19 health orders, and many haven’t been bashful about tattling.

They submitted 89 complaints in November and 18 through the first week of December. Most of the complaints, which this news organization has reviewed, clearly lay out the unsafe practices that customers said they witnessed.
