There are many, and even if they do not have a part in ownership someone will get to the manager there(or other) it's whole thing to who gets what shelf and where on the shelf and where on the isle.

The person with the best shelf(eye level) and the best spot on the shelf and where on the isle is usually kicking up !!! or the made guy has part ownership in that product ..

It is a very good and almost legit racket ,I think it was PB says just doing favors for friends. If there is a money trading hands (so be it)....
