Having the drink available in the soda fountain next to normal drinks is overall a bad idea both for kids and unknowingly customers (also ~400 calories for a lemonade is madness). The adjective "charged" doesn't make me think "with caffeine", it should be called caffeinated/energy lemonade in big font like redbull does, not with some abstract marketing adjective.
It is also next to other normal lemonades like it belongs there and not in the "coffee" section.
