Admittedly, it may not be practical if you are already late for work, but using my technique you can replace a rear drive-side spoke without removing the cassette. And many pliers have a built-in cutter that is perfectly adequate to cut a spoke. But you certainly could carry a ready-cut spoke if you are nervous about finishing a day's commute with a broken spoke.
