From reading firsthand accounts out of Italy, after the initial panic the shelves stayed pretty well stocked.
That's what I'm banking on.
Oh, I've got plenty for myself and family and we'll be frugal.
But people ain't going to eat all that easly and it's not like the infrastructure is down. Trucks will roll, Mfgr will be making stuff, electricity is on. The shelves will get stocked after the initial hoarding is over.
