Hayley held herself out as a principal while negotiating the purchase of a large stock of cosmetics and perfume from Rockland, a retailer that had run into financial difficulty. In fact, Hayley was making the purchase on behalf of her employer, So-fine. Rockland was unaware that Hayley was employed by its competitor So-fine; however, Hayley gave the So-fine address as the delivery address. Upon delivery, So-fine changed its mind about buying the goods and refused to pay and rejected the goods. Advise Rockland.
