You shouldn't have to lie to the store people about why you want to purchase a certian product! It really is none of their darn business and I think it is highly intrusive of them to even ask! There aren't any of those stores where I live, but if it had happened to me I would have told the girl at the counter that it was none of her ~#$% business why I was buying the ketostix AND I would write a letter to the corporate office over this travesty. No one has the right to regulate to whom they sell their items to, this is downright discrimnation. NO one should stand for it. A Boycott of the store seems to be in order, and I don't mean a quiet one. I would make sure that everyone I knew, and plenty of stangers heard about these stores unfair practices.
