There are a pair of swans that come into Torquay Harbour fairly often. The problem is the Harbour has a sill at it's enterance and the poor swans can only get in or out at high tide. So when they try and leave at low tide they are stuck and get a bit nervous. A cigerette at a time like this is just what a person needs to pass the time until the tide comes in again.
One of the swans had a tag, blue with yellow letters CS/JS. A little wander round Google didn't come up with any way of finding out more imformation about these swans. I am guessing they are a pair but don't have any cygnets at the moment, they are unlikely to have left them alone for so long.
