Let me explain. Some time ago, I was browsing the chilled food aisle of my local supermarket (yes, I do occasionally eat things that don't come out of tins) when my attention was caught by a tin on one of the refrigerator shelves. My initial thought was that it was something left there by one of those people who pick up an item, change their mind half way round the shop and then deposit it on a shelf wherever they happen to be at the time, the rogues. But no - there were a number of the same tins on the shelf - the product had clearly been stacked there intentionally. But what reason could there be for keeping tins in a fridge? The whole point of them is that they keep food preserved at ambient temperature.
