I can't remember the last time I ate anywhere because of an ad. I eat out a lot too, used to uber eats nearly every single day. I wont reorder at places that mess up my order, but consistent quality I reward. Chick Fil A gives me the best service out of any fast-food restaurant, so they earn my repeat business.
People almost never admit it when they respond to an ad. Even when they very clearly do.
Don't underestimate the effectiveness of advertising, or its ability to influence you.
