I'd think rather than giving you shit about your top score on the exam, he'd have been concerned that perhaps the scantron marked those wrong for everyone in the class, which could made a grade-letter difference for others who might've had scores on the cusp.

Anyhow, congrats on the exams, yay for your gran and your pup, and hooray for no longer working at the bad place. Fuck them in the facehole with a knuckledustered fist.
