Exactly.
I was a contractor and could have been out of work with no notice. Just to be safe I kept a couple of months worth of basics on shelves in the utility room.
A year ago, aware of COVID, I got a Booker warehouse card, more shelves and a 200L chest freezer. Now I have food, cleaning materials, bin bags, toilet paper and all sorts to last 6 months or more. I also bought FFP2 masks, Clinel wipes and other infection control materials.
I don't want to rely on JIT and having to scrabble for food if there's panic buying. It's my responsibility to look after myself, my household and, if they have not planned for themselves, my immediate family.
This is my new normal.
