Only essential businesses can be open. Everyone else is supposed to be at home. New rules go into effect Tuesday. They waited for a few days to give people time to take care if personal business.

So, naturally , everyone is trying to get all stocked up before Tuesday. And so thousands are all mobbing the stores. Not just the
Virus but flu is still out there as well.

The essential stores will still be open. Even laundromats can stay open. No reason to completely panic.

Hours based on last name but who would police that?

Here in Nevada supermarkets were swamped at first but things calmed down a bit after people were stocked up.

When it begins to get busy, they get everyone to line up outside at least a shopping cart's distance between. As people leave new people are admitted. Those just there for prescriptions wait in a separate line. They are escorted to the pharmacy in small groups.

Checkout is similarly controlled. One long line of shoppers extends from the checkout towards the back of the store. All of the cashiers are open, so the line moves quickly, but there's no clustering around the checkout.
