Wouldn't it be a problem for the restaurant if people were contently sending food back or being disappointed by the product because it didn't look like the ad? I mean, the difference is striking! (see https://i.imgur.com/e9EaVbu.jpeg). If I genuinely expected the first burger in that image and got served the second one I'd demand my money back and maybe never step foot in that restaurant again! Wouldn't most people? It seems more likely to me that most people accept that the first burger is a fantasy.
