I did wonder.
There have been articles in the media today, with quotes from Tesco (don't panic Mr Mainwaring) and Iceland (och we're all doomed) regarding Christmas stocks - for which the build up has (or should have) now started. But the ones I read were remarkably lacking in detail such as whether the problems are in the breeding/growing stage, culling/harvesting, processing, producer to warehouse delivery, warehouse to store delivery, or stocking of shelves.
In the absence of detail I dismissed it merely as press releases designed to generate headlines for which the rushed/lazy journalist is eternally grateful. I do like some analysis behind the headlines. I think the Tesco person spoke of 30 to 40 deliveries per day being missed, compared to how many thousand would they have in a normal day?
