UK 4 meals away from anarchy in a disaster?

[bigpaul]

shops in the UK carry 3 DAYS worth of food at any one time, its called the "just in time" food delivery system, in normal times that's enough, but in an emergency that will be gone in Hours not days, during the recent snow storms I heard of 2 guys(some said it was females) in Sainsbury's in Marsh Mills in Plymouth, fighting over the last packet of crumpets in the store, that might just give you an idea how unprepared most people are.
