ANTIOCH —  At Lumpy’s Diner in Antioch during a recent noon hour, table servers were taking orders, customers were chatting over burgers and cooks were furiously whipping up entrees in the kitchen. It looked like a typical busy eatery, with a couple of big exceptions.

The restaurant’s co-owner, Gena Noack, wasn’t wearing a mask while making the rounds greeting customers, despite a Contra Costa County mandate to do so. Neither were most of the dozen or so workers that day, though most customers wore masks while walking into the diner.
