Brown's Chicken - NOT SAFE

My son was invited to a party where Brown's Chicken was the menu. Well, a call to Brown's Chicken hq was transferred several times and I had to conclude that they dont get this inquiry often, and that they don't really know who knows about their allergy practices. Finally, a customer service rep said that they cannot speak to allergy safety at all because their vendors are ever changing and they cannot represent their vendors' practices or ingredients. So we'll just skip all food from Brown's.
