Sainsbury's - a bit like Helm's Deep

I was in Sainsbury's quite late last night - picking up the glasses for our Carol service on Sunday. It was eerily quiet but there were LOADS of teenage staff stocking the shelves...stuff everywhere.
Today (Saturday) is supposed to be the busiest supermarket shopping day in the whole history of the planet or something. So they were preparing for the onslaught.
It kinda reminded me of the scene in 'The Two Towers' where all the good guys are in Helm's Deep preparing for Sauron's army which they know is coming!
