For food shopping this Christmas we noted our local Sainsbury's, in West Hove, would be opening much longer hours than usual.

We duly arrived on December 23 at 10pm with a bulging wallet and lots of enthusiasm but, to our dismay, discovered many shelves were empty.

Even essentials such as bread and milk were gone.

What is the point of supermarkets opening all these extra hours if they can't refill the shelves when needed?
