People were more than happy to share at first, because they figured after a few days the local governments would have their acts together.
And some people are frustrated - for example, my local grocery store arbitrarily decided at 1pm or so on Saturday that they would limit sales of water, canned goods, etc. per customer.
So people were on line waiting patiently with carts full of groceries and were told that the cashiers would only ring up a small percentage of what they had in their carts, while they watched other people cramming their cars full of goods outside the store.
It's hard to say that the person who got to the register at 12:59 was truly a wise ant and that the person two places behind them in line was a foolish grasshopper.
In many cases it was luck of the draw.
BTW, my wife laughed when I bought pounds of jerky. Not too many uncanned proteins last very long.
We have over a years supply of freeze dried food. But then we live up in the Olympic Peninsula miles from anywhere. We’re all pretty self sufficient. Preparedness is the key. I don’t think that city folk have that presence of mind to prepare.
