I went to my local Fareway and Walmart about the same time last night. Full size WM in SW CR. Both were rather chaotic.
It look like the WM grocery section had been looted, and I had gotten there maybe an hour after the looting occurred. Kinda like the calm after the storm, "too late" shoppers wandering around picking through what was left.
The canned foods aisle, the frozen veggies section, most all the cheese, rice and noodles section, TP and paper towels aisles, breakfast cereal, bread, all canned soup...all picked clean empty. I remember seeing a father with his roughly 8 year old son - on the phone saying to apparently his wife "looks like we're not having corn either. There is no corn, no veggies...the shelves are empty".
The Fareway was the busiest I had ever seen it, over a decade of going there. They were decently stocked, but every cart was in use and there were some empty aisle spots here and there (I was there for only a couple "Friday only" deals). The meat counter was jam packed, didn't even try - I would have waited a good 20 minutes, maybe 50 people deep.
Damndest thing I've ever seen. Crazy...
