I happen to know that at one time the Eastern Europeans where going around all their local food banks and pickng up a bag of food at each one so they did not have to buy any groceries.
The local Government Offices now give people a voucher for food, so the really needy do get their allocation and there is no cheating.
This is from someone who works at a the local Goverment Offices, apparently the very needy are really not trying it on, a lot of them are working single parents who just don't have enought money left after they pay their bills for food.
If you find out where your local drop off point is, you can hand in a bag of groceries, they ask for tinned and packet items and things that will not go off. This is a very worthy cause.
