'They need to be protected,' Pleasant Hill woman leaves handmade masks on front door for delivery workers - KTVU Surveillance video shows a UPS driver making a delivery in Pleasant Hill. It Iooks routine enough, but after he sets the package down, he notices something on the door: three handmade face masks and a sign asking delivery drivers to please take one because "we want to make sure you stay safe." "Aww thank you. That's awesome! Thank you," the delivery worker said in comments captured on a Nest camera.
