singing, DG - My musings on possible shortages and rationing ...
I expect anyone like coeliacs needing special foods, or anyone with allergies is just going to be left to sort out their own limited diet from the available basic food stuffs.
Not great for those with little education or knowledge about possible substitutes for their condition.
The NHS probably won't have large stocks, even for those who have such foods on prescription.
Too many people think such folk are just "fussy" anyway, so they'll be given at most a leaflet of (probably impossible) advice
Even worse, think of those kids - and adults - with SN who would literally starve themselves to death rather than consume anything outside a range of a few foods & drinks.
According to senior civil servant JDD on RNorth's blog, there will be a ration card like a credit card.
But that has limitations: weak signal, or power cut to the machine reader in the shop ...
In WW2, people had to register with specific shops.
That worked, because most folk lived in the same place all their lives.
ALso, there were no supermarkets and self-service, so each item was personally handed out to each individual.
(I actually remember when Mum, Dad & I visited the first supermarket in our area, early 1960s. New-fangled idea fronm the USA. Exciting, but we wondered if it would really catch on !
I think now it was about the size of a petrol station Tesco, but then it was amazing to have so much in one shop and to put things in our own basket)
How could people register with one supermarket and than have it administer their personal rations ?
How would a system without specific shops work - like a bank account, but for grocery allowances instead ?
Whatever system - if any ! - I fear that the IT wouldn't work - not enough time to develop and test it.
Maybe go back to the 1940s (which would delight some Brexiters) and use paper ration books, at least as a backup.
