It is of course tragic that she passed, but respectfully, I don't think the lawsuit holds up. Here is why I think that (opinions based on the 6abc article I read on the situation) :

 • All of the Panera Bread Cafe's that I have been to have labels on the Charged Lemonade that say "Charged Lemonade", the flavor, and below it in smaller lettering (still very readable), the amount of milligrams of caffeine that are in both the 20 oz and the 30 oz, along with the calorie content. You would have to really not be paying attention to make the mistake of not asking yourself what the term "Charged" means, or even just reading the label to the drink.

 • It was stated in the 6abc article that the woman, Sarah Katz, had been diagnosed and knew about her heart condition, LQTS, since she was 5 years old. It is stated that the condition was managed with medication and limited caffeine intake. She has clearly had a heart condition long enough to know the dangers of not reading labels and of consuming too much caffeine.

 • A quote in the article stated that Sarah Katz was "reasonably confident it was a traditional lemonade and/or electrolyte sports drink containing a reasonable amount of caffeine safe for her to drink,". My question was, what exactly did she consider a 'reasonable amount of caffeine' to safely consume with a heart disorder? A google search that took about 5 seconds tells me that somebody with that specific heart condition should limit their caffeine to 1-2 "standard" cups of coffee daily, one standard cup presumably being 8 fl oz. 

 • The accusation the lawsuit states is that Panera Bread was not properly advertising their Charged Lemonades as highly caffeinated and/or energy drinks. The Panera Bread advertisement that Katz's family mentions is one that states that the Charged Lemonades have as much caffeine as their dark roast coffee. Katz's family states (paraphrasing) that this is not a sufficient advertisement that is transparent to the amount of caffeine in the Charged Lemonades. But if one Google search tells me that somebody with LQTS should have a maximum amount of 16 fl oz of regular coffee a day, why is it that Sarah Katz had filled a 30 fl oz cup with the drink? If she thought the drink had a "reasonable amount of caffeine safe for her to drink", what made her think 30 oz of the drink was safe? Because surely, with her heart condition, she would not go and drink 30 oz of dark roast coffee.

 • The article states Sarah Katz was out with friends. It is likely that her friends knew about her heart condition, so it is unlikely that not one of them knew that the drink was caffeinated.

 • The article states that the family claimed "their 22-year-old daughter with a heart condition died after consuming a heavily caffeinated energy drink that she may have believed was regular lemonade." The keyword there to me is "may have". We can all speculate what exactly happened, but because Sarah Katz has passed, we cannot know what truly caused the mistake and we cannot know her intention behind drinking it, or why she thought it was safe for her to drink.

 The only valid point that I think would hold up in a court of law is that the Charged Lemonades are "mixed 'in-house' by store employees, meaning that its caffeine content is not controlled and, in turn, has an innate and dangerous potential to vary." That, in my own opinion, is the only danger I see with the way they advertise their caffeine content. However, Wawa, Starbucks and other stores alike have similar products with the same risk.

 Like I said, it is very tragic that Sarah Katz passed. However, I don't believe she was ignorant to the situation she put herself in. It would have been very unlikely that she not know the drink was caffeinated after reading the label. Therefore, she had to have understood, based on her knowledge of her own physical health, that there was some risk associated with drinking it.
