I have been burned like that before.One time it was probably a days worth of work, but split over evenings of my free time took longer, so I didn't finish it.

Another time it was as if some junior developer was circle jerking. Whining about the most trivial things (a couple of whitespace errors in Pylint, not returning JSON when they had requested a "page without styling", Not adding a setup.py, when they didn't ask for it. )
