I can never recall, running out of bread, butter yes, even sugar, but never bread,
That was when my mother baked every day.
Running out of bread is a modern phenomenon, only since this rise of fake flour.
Mass production of homogenous, commercial, processed, full of all sorts of preservatives, stabilisers and colourings, with an endless supply chain, is why people run out of, quantity bread.
The difference between now and the future, is, sell by date, but not eat by date, though, best before end of wrapper is always there after the list of ingredients which nobody reads or understands.
I never run out of bread, because I never run out of flour yeast or water.
