When I said "not to leave people in a position ..." I wasn't really thinking of people in the UK.
If you can walk into hospital then you're not going to be treated for hunger, if you can't then you'll possibly die where you sleep. I'll agree, in winter in the UK you'll die from exposure before you die technically from starvation.
Yes, in my city the best (in fact only) street work is paid for by the local Church - they do a rolling program of food/shelter moving between a few of the city centre church buildings.
"Finally, if you somehow manage to be completely unable to find food anywhere"
Isn't the point kinda that you can walk into this huge building, nearby and full of food, 20% of which will probably just be binned, and help yourself??
