I went grocery shopping Sunday morning and they had tape up preventing entry into the produce section directly from the entrance and directing traffic around the adjacent bakery, deli and cheese sections in order to corral everyone checking out into a single line for checkout along one wall far away from the cash registers. There were no explanations, so I thought they were limiting entry (even though no one was monitoring it) until I saw that a line had formed and there was an employee directing people to cashiers. Fortunately by the time I was done there was no line, and it turned out the employee managing the flow of customers was also checking to see if you had more than one item that was being rationed.
There was absolutely no toilet paper despite signs limiting purchases (fortunately I'd bought some early in the month and didn't need any) and very little bottled water, but what got me the most was that the 18 pack of large store brand eggs I normally buy for $2 or thereabouts was completely out. I bought the least expensive eggs I saw, which were a dozen store brand brown cage free organic for $2.50. Unsurprisingly, egg purchases were also limited to one per customer along with bread and milk (there were adequate supplies of both, but I use lactose free milk, so I don't know about regular milk). I can already tell I'm going to need more bread, though.
The store wasn't crowded, but people weren't always staying the recommended six feet away. (And in some cases it was impossible - the aisles aren't that wide.) If I'm already stopped to get something, please don't stop within six feet of me, for crying out loud!
