I went to the supermarket this afternoon. The parking lot looked about normal for a Friday afternoon ... but that's probably because there's nothing left to buy! There was ZERO toilet paper, very little in the way of paper towels, almost no facial tissues, and all antibacterial-related cleaning supplies had been wiped out. Also, no bottled water.
I was there to do a mostly normal weekly restock. Once I saw that we're in doomsday mode, I bought a bit more than I would usually have bought, but not a lot. I should be good for a couple or three weeks with no resupply at all. Dunno what happens after that. (I guess if I have to go to the market after a couple of weeks, I'll wear trash bags and be a fashion icon.)
