Mr. Douglas Millican:

In simple terms, one can. The type of situation that we tend to encounter does not involve wilful abuse. In the case of, for example, a small supply to an island community, someone who has a holiday house might happen to leave a tap running when leaving the house. If there is excessive consumption like that in an area, we can discover it and deal with it. I would never call it "wilfully abusive". It is just the sort of thing that can happen.
