Pizza is not that bad, depending on how you put it together. As an aside, if these folks were really thrifty they’d cook the stuff at home.
It says in the article, these are the places people go when they want a break from cooking at home. As chief cook and bottle washer in my household, I do understand. We've trimmed down to dining out once a week and sometimes it's Subway. I do appreciate the break, even though I love to cook. :)
