If there’s a big sign that says “Plant-based, clean caffeine powered by guarana & green coffee extract” with “30 fl oz | 530 cal | 389 mg caffeine” on the sign she was staring at when she poured her drink, that might make things a bit complicated.

The Panera signage seems obvious enough about caffeine that (assuming the signage was in place) I can’t imagine any more correct action Panera could have taken short of having a person stand there asking people if they have heart conditions.

I mean, imitation crab meat often has trace lobster in it and nobody advertises that. It falls under “let our associates know if you have any dietary restrictions or food allergies”. Did she say “I can’t have caffeine” and then they let her fill her cup with charged lemonade? This is a beverage that is marketed on being caffeinated, and every piece of advertising, signage, etc features the caffeinated nature prominently because it’s a major selling point of it.

Nobody should be blaming her. But unless this Panera did stuff very different from the Panera standard, it was sufficient.

And you’re right about the legal implications of her medical condition. But I don’t see many people suggesting it’s her fault because she had a heart condition.
