There’s nuance, right? Like, it’s on you to know that beer has alcohol in it. It’s reasonable to assume that hard cider that’s sold alongside beer and liquor will have alcohol. It’s also reasonable to assume that the seltzer that’s sold near the rest of the seltzer doesn’t have alcohol in it. But if it says it’s “hard” seltzer, there’s an argument to be made that you’ve been warned that this seltzer is alcoholic.
But “charged” is not a standard term to denote caffeine, and this lemonade is not nestled between coffee dispensers. It’s perfectly reasonable to assume that the lemonade that you order doesn’t have caffeine, because lemonade doesn’t normally have caffeine. If you ordered a root beer and got something with alcohol in it, would you say the same thing about being aware of what you’re consuming?
