most of retail is packaging branding and marketing
it's a science to everything in the presentation. some of these things just click when we see them, hit on visually pleasing points and peak some subconscious antennas. especially the colors. when you strip all the presentation and just call it chicken strips you expose what it is in its bare element. people are there because of successful marketing.
people were going nuts for the popeyes sandwiches swearing it was something in the food when it really was a combination of social media hype and marketing. mania (hysteria) can be contagious, this was noted decades ago. people don't even realize how much so. We don't like waiting in line but we hate being left out even more.
If you want to do a very revealing social experiment on some basic human psychology just go to a public place and try handing out small free stuff and nobody will want it if you are alone and trying to convince them to take some from you. once you have some takers and a line starts to form more people get curious and just start rolling with the program and there is a demand all over a sudden. same people would reject whatever you tried to hand them if you were alone all over again. Once the opening hype settles down and the lines die down you observe this very same phenomenon. you can walk in and get that chicken sandwich with no effort today people fought for and lined up for for hours with ease and the demand isn't the same. some people even convince themselves they changed the recipe.
human psychology is fascinating.
