You gotta be pretty sensitive to consider momentary awkwardness a consequence when someone blamelessly and passively corrects you.

How do you reckon that they were judged here at all? This is a level of transgression roughly equivalent to mispronouncing someones name for the first time, I can't imagine anyone else even remembering this incident aside from OP and even they may only remember because the human brain reserves 10% of its space for reliving minor faux pas.
