I'd build his/her CRUD app, and make sure it wasn't shitty, if I felt it had potential to be a useful product and also felt like the people I met would be good to work with/for. I've learned the hard way that I much prefer quality of life over "sexy dev work." (...and obviously take both if I can find it.)
