Cui bono?

This is a title that I have used before more than once - it means "who benefits?" (strictly speaking "to whom the advantage?") and it's an approach that I have always found useful when assessing any change in rules or regulations.  So, following on from Friday's post, who will benefit - or benefit most - from this decision to scrap sell-by dates on food packaging?  And it seems to me that the main beneficiaries will be the supermarkets, who will be able to keep food on the shelves for longer.  At present, once an item is past its sell-by date they have to take it off display and probably throw it away.  Whether the knowledge that this is no longer happening makes you feel any more comfortable as a shopper is altogether a different question.
