This morning at the Publix at Lake Deaton I heard 2 employees in the bakery discuss how some other workers will be working overnight to do just that, clean, sanitize then restock. When they're re-opening I don't know but I do know most items on their shelves come in from one of their 3 regional distribution centers and I'm certain all of those are at full capacity receiving goods then getting that inventory out to their many stores.
