Here in Ontario, Canada, all the grocery stores to give the workers a break. However this is also Good Friday & Easter Sunday. Stores could be open normally on these dates. The workers do deserve a break..
it seems here that some stores do not restock to keep people away so they can run on a smaller crew of workers and restock on certain days. I have confirmed this with a few places i frequent.
Most of the local (Naples, FL) grocery stores are operating on reduced hours and will be closed on Easter. You still can't get paper products, anything that resembles a sanitizer product, or dust masks. What I did find that was kinda wierd was that yesterday my bride had to shop three different grocery stores to find a particular kind of yeast that she needed for baking an Easter bread that she makes each year. People must be taking up breadmaking during this shelter-in-place time.
