This is what is known as upselling, and having managed fast food in my younger years I can tell you with absolute certainty that yes, it is predatory. Customers have food in mind that they want, they order it, and then all of your employees start trying to upsell drinks and fries. If the costumer wanted them, they would have ordered them. But this simple question gets an enormous amount of people to buy $3 soft drinks that cost 2 cents to make when they otherwise wouldn't have.

ROFL AHAHAHAHAHAH OMFG OMLLLLLL LOLOLOLOL AHAHAHPsychology is not exactly science.
Oh god, you caught me off guard with that one. Yes, Psychology isn't science. Neither is biology if that's the case.
I get what you were trying to go for though. You were trying to claim that psychology isn't accurate, which is patently false. The conclusions of psychological studies will not always apply to every single person. But the number of exceptions are far fewer than you would think. People are incredibly easy to manipulate. One day when you grow up, you might learn that. Either that or you'll be one of the manipulated ones. And if you're grown up and you haven't learned that people are incredibly easy to manipulate with psychological tricks... Well... that's unfortunate for you now isn't it?
