This interesting prank/experiment shows the dissonance of the whole supermarket culture.
The customers are delighted to try the sausage at the beginning. Yes, they know it's a pork sausage, and that pork is made from pigs. But they're thinking of a tasty sausage.
Once they see a piglet, their whole attitude changes They're thinking of the cute piglet. And then the sausage comes out.
They are visibly nauseated. Horrified. Distressed. And angry.
What a great ad for vegetarianism!
