In my case the pandemic was not a stress test for my preps. It did not even get close. There where only two items I couldn´t purchase in stores temporarily: corned beef and toilet paper. I did not run out of either.
I had the ingredients for hand sanitisers. They still where available e. g. in electronics shops too.
I evaluated my supplies to determine if I could get through 14 days of quarantine. I could and have left plenty to go.
As expected the hoards did not come to my door to loot my supplies. I chose to ignore the griping of others when they complained about shortages. That worked out well too.
Basically all the hoarding in Germany was done in panic. When one person starts it others feel the need to follow. I do not even want to know how many people bought canned goods they do not actually like just to have supplies. I wish them good appetite when they start consuming the stuff.
