This shit looks like lemonade to me. If I’m not specifically looking for the calorie content, I’m gonna filter out that caffeine content just like everyone else. A few hours later when I get the jitters, I’m never gonna be able to trace it back to that small yellow text on a green sign that I didn’t read because I’m not avoiding calories.
To your other point. I probably wouldn’t question it, because burgers typically don’t have alcohol or caffeine in them. Here’s a better comparison: you go to a restaurant you’re unfamiliar with and order the “Jacked BLT.” Does that sound like a marketing word, or a description of what comes on the sandwich? Because I would bet most people would order that sandwich expecting bacon, lettuce, tomato. I expect most people wouldn’t expect six scoops of vanilla protein powder, even if it says it comes with that in the fine print next to the nutritional information.
