The author's sales data is for undergraduate students, so extrapolating to family meals may be misguided. That said, I think quantity is key here. There may be a correlation between "concern about calories and transfats" and "need to price discriminate". Those who's buying patterns are less price based (higher income and higher household income while being raised) are possibly more likely to be worries about their consumption habits, whereas buyers for whom price is a big deal want to maximize caloric intake for their $$. Thus, McDonalds is successfully getting a reasonable margin for natural 20pc buyers, and double that for 10pc buyers who wouldn't care about the price anyway.

The author is also a Dartmouth student, so his customer base of undergraduates is not exactly the same as most samples of undergrads. Ivy League students tend to be a lot less price-conscious. The bigger question, is whether his service operates late-night. With Gusanoz gone, pretty much the only option for late-night drunk food is EBAs, home of the most godawful and expensive pizza I've ever experienced. If somebody opened a 24-hour hotdog cart or something and parked it on Webster Avenue, they'd make a killing.
