Or you could, you know, make breakfast for your friends. I don’t really get the brunch lines thing. Most of the food is pretty easily made in even a minimal kitchen. (And bread can be bought the day before.)
I'm guessing people in tiny apartments may not be able or willing to deal with a bunch of friends crowding it in the morning. Or maybe they don't live near each other, so they'd rather brunch near the office. Or would rather brunch during a work pause, rather than before getting to the office.
What working people have brunches with friends during the week--except perhaps on a very rare basis?
I'll grant the tiny apartments but I'll also observe that, in undergraduate, we had space for a sizable number of people in a shared kitchen area. If where you live once you start working in a tech job is a downgrade from college, personally I consider that a problem.
I mean, this isn't just brunch around here. A dinner spot that would be one step above counter service in a larger city can have a line out the door in a smaller one because there's just that much less competition
