While I am skeptical as well, there are a few other scenarios that aren't being considered in your napkin math: - Selling items other than crepes: coffee, tea, alcohol, soft drinks, snacks, etc all have great margins. - If the place is a cafe, customers may stay and work/read and run a tab, increasing the average revenue per customer. - Multiple customers may arrive as a group and run up a higher tab. - Multiple locations: compounding revenue, higher reach, etc There are probably many more things I'm not even considering.
