Steve,
What the problem is, is that there have been lawsuits between the companies over this very thing. The major companies pretty much agreed to disagree on the issue. SOME of these companies WILL fill the smaller ones because they aren't their major market. They still are likely stolen. The big bottle business was what was the major problem. Its their core market. They can live with losses of the small units and do turn a blind eye to it. They have all settled to allow the smaller ones to be filled, though technically its NOT their property.
