Abstract :
There??s a famous moment in Lewis Carroll??s `Through the Looking Glass?? when Humpty Dumpty says: ??When I use a word, it means just what I choose it to mean ?? neither more nor less.?? I wonder what Humpty would have made of this recent announcement from Virgin Trains in response to complaints about its online booking service: ??Moving forwards, we at Virgin Trains are looking to take ownership of the flow in question to apply our pricing structure, thus resulting in this journey search appearing in the new category-matrix format ?? I hope this makes the situation clear.??
