Again. Looking at the sign. What I see is three lemonade containers. They look exactly like every other lemonade container I’ve ever seen. I’m not reading the little text at the top or bottom, I’m reading “Mango Yuzu Citrus,” “Strawberry Lemon Mint,” and “Fuji Apple Cranberry,” and I’m gonna fill up my 30 oz cup with that Fuji Apple Cranberry, because it sounds like a good flavor. I’m not gonna read the marketing fluff, and I suspect that the vast, vast majority of people, yourself included, would never think to, if the only information at our disposal is those signs.
But if you’ve already made up your mind about who was right and who was wrong, I can absolutely see you convincing yourself that of course she should have read the marketing fluff, despite the fact that she had no real reason to because lemonade doesn’t typically have caffeine. This conversation will go absolutely nowhere because there’s no way for me to convince you that A) it is normal to ignore the marketing fluff, and B) it is not normal for lemonade to have caffeine, and so C) Panera is in the wrong in this by not making it abundantly clear that one large cup of this lemonade would contain more than the daily recommended limit of a psychoactive drug.
I would say that they shouldn’t be able to sell individual drinks that contain that much caffeine in the first place. Like I’ve said elsewhere, 30 oz of coffee is too much coffee. But at least you know what you’re getting into when you drink 30 oz of coffee. So the bare minimum is to make it wildly clear, like super duper clear, that this lemonade has this much caffeine. Make it part of the sign, in text as big as the flavor. It should simply not be possible to accidentally order a drink that contains so much caffeine that it can kill someone with a heart condition.
