What would The Fat Controller make of it?

Train fares - complicated or what?  I think most of us are now aware that if we are travelling from A to C going via B, it may well be cheaper to buy a ticket from A to B and then a separate ticket from B to C - this makes no sense to us as commuters (presumably it must do somehow to the train operator) - because it is exactly the same journey.  But the ultimate idiocy of this sort must be the case of the man who occasionally commutes from Preston to London at a cost of £350 and who found that by catching the train (same train) at the earlier stop of Lancaster he would only have to pay £93, a saving of over £250 for travelling some 25 miles further!!
