I definitely make a point of keeping a small stock TP (and cheap/easy food, like bologna, hot dogs, and bread) around in these post-covid days.

Not to the extreme of the story about the soap, above, but: Something in my mind was changed a little bit more every time I'd go to the store and there were empty shelves. So now I do things like always have a few weeks of TP, and I freeze things like bread and bologna.

I never did that at any point in my adult life leading up to COVID: If I ran out of something, I just picked up more later at the store the next time I was nearby (or any other time; lots of things were 24/7 back then).
