The family of a 46-year-old Florida man has filed a wrongful death and negligence lawsuit against one of the biggest fast-casual restaurant chains in the U.S., claiming Panera Bread Company's caffeine-filled lemonade drink led to his death. David Brown had high blood pressure and didn't drink energy drinks, but the lawsuit said he believed the Panera Charged Lemonade was safe since it was not advertised as an energy drink. It was offered in the same place as the restaurant chain’s non-caffeinated or less-caffeinated drinks, according to the lawsuit filed Monday in Superior Court in Delaware, where Panera Bread Company is registered. The lawsuit states that on Oct. 9, Brown had the drink three times during a visit to the Panera Bread Company location in Fleming Island, Florida. On his walk home, he suffered cardiac arrest and died a short time later. He had ordered a Panera Charged Lemonade at least seven times over the course of two weeks in September and October, according to the lawsuit.
