Last year when we were down here in Devon we noticed that there were quite a few oil tankers, just sitting there out to sea. They did not appear to move from day to day. The rumour was, that they were waiting for the price of petrol to go up.
I found that difficult to believe, but what do I know? Yesterday I was watching a programme about supertankers, and lo and behold, that is exactly what happens.
So if you live near the sea and see them all lined up, just sitting there … you can astonish your mates by announcing, like an oracle, that the price of fuel is about to go up.
