IF Sherlock Holmes & Dr. Watson were on the case, I am pretty sure that my two old mates would have thought along the following lines.
Watson: I say Holmes, have you read the complaint about Bus Fare increases?
Holmes: Yes, and I have deduced that the clues into clarifying this delema are within the senders signature.
He is a boy, aged 2, and therfore is not aware as to what is going on in the real world.
But supposing that the boy, as you say, turns out to be an adult.
Holmes: Well Watson, if that were to be the case, then this person could have a legitimate complaint.
Watson: What would be his complaint.
Holmes: The cost for this man, to go and collect his dole and other benefits has increased. Therefore he will have less to spend on beer, fags, and betting.

In closing this case - up yours mate.
