Obviously I didn't see it coming either, though you did get a vague form of foreshadowing in the form of the Little HR Department That Couldn't. Companies that are that screwed up in SG&A generally have bigger issues that often result in strangeness like you just experienced.

Remember why I fired my previous employer (discovering three and a half months in that HR had dropped the ball on my insurance, a common occurrence apparently if other people's tales are to be believed, and upper management circled the wagons rather than taking disciplinary action).
