Should food look like it's advert?

On both sides of the pond people are complaining about burger chains that show pictures of large meaty well filled buns but serve something that looks like it's been sat on.

They argue photos don't have to look like the product and people should be smart enough to know. But customers say it's false advertising and more than just a little embellishment.

Thoughts?
