I found this image from someone's blog online. It was apparently someone who went to Wendy's expecting a Baconator sandwich that looked like the one in the advertisement on the left. The Baconator the person received ended up being the one in the picture on the right. This person was very unhappy with their Baconator. This shows that food advertisements can make different foods look extremely delicious, when in reality, they looking nothing like the image.
I think people get angry very often with this issue, but don't really do anything about it because they are going to eat the food anyway. I feel as though advertisements that make food look much better than it really looks deceives the target audience and makes them think they are going to get something much higher quality than they are actually getting.
