Wow. That's friggin scary.
We had nothing like that down here.
Our PM gave the country 48 hrs to prepare for the country-wide lockdown. That evening, my wife went shopping for our usual amount. The next day, I had to pop into the office to grab some stuff (working from home for 3 weeks now) and saw that the grocery store carpark was 1/2 full. I decided to pop in and "really" stock up.
I couldn't believe just how chilled out and orderly everyone was. There was a bit of tension in the air, but everyone was also uber friendly with each other, but kept their distance.
That said, we've heard stories from overseas about panic buying and all that.
Man, it'll be great when we are all back to normal again. (Whatever normal will be.)
