We ordered 4 spicy chicken sandwiches and nothing else. We ate the sandwiches on the way to our home in Ouray. Early the next morning we all experienced the worst case of vomiting and diarrhea we have ever seen. We all were throwing up clear liquids that smelled like hydrogen peroxide, there wasn't anything we could keep down. I believe that there was cleaning products in our chicken sandwiches that cause the intense reaction.
