Please, these rules are very good for professional food care, and I like to
think that any restaurant does take *absolutely no* risk with food safety,
but let me state that these rules are absolutely overkill for most every
normal life situation.

Don't make me say what I didn't.
They knew far better than today what can be held and how long, before
contamination goes from anecdotic or tolerable to dangerous. They didn't
know about germs but they knew that one wouldn't come ill after X days but
most certainly would after Y days and so they could take risks until X-1
days. Today, and mostly in the US the motto is *no risk* and so nobody
knows anymore what the limits are because when the first bacteria appear in
mostly harmless amounts the products are already thrown away.

Then again I don't say that security is bad, but when you have to take
risks or starve, you will take calculated risks and become good at taking
them, and when you don't have to so much the better.

Could apply even to Sunday's leftover chicken ; carve as much meat as you
can from the bones, drop bones in stock-pot, reheat meat quickly and seal
with lard, should keep a few days, but it is far more risky than serve the
cold chicken monday noon, which will do without problem.

Life without a fridge can be a lot of work, but then again, people had to
do it, so they did it. Women mostly didn't work out, rich people often had
a maid, and work was done. Our modern times are very labour-saving and
that's a good thing too.

Drafts can suck up a lot of moisture, and bring in a lot of
micro-organisms, so just like parakeets sensitive food should be kept out
of them, except if you want it dry.

Ah for a mayonnaise based salad I wholly agree with you, why did I say keep
things separate, pure mayonnaise can keep unrefrigerated quite some time,
potatoes or pasta too, the meat is the most sensitive ingredient. And as I
already stated when you don't have to take risks by all means don't take
them.

It seems our positions are not so far apart, I just would like to remember
that there were alternative means of doing things.
Once again, for everybody, play safe, know your limits, and do not take
chances with food, they did what they had to do, we don't have to.
