Over promising and under delivering.
Case in point, my local Dominos Pizza. I tend to have a pizza on a Friday evening. I see a photograph of the one I want on the website, I read about all the delicious toppings and can see that tasty mozerella cheese dripping off the garlic bread and the rich tomato sauce spread lovingly over the base, much like the one in this picture actually.
What do I see when I lift the lid ready to enjoy the tasty delights inside?
