my boss apologised to him and explained what was being played and for what reason. She is in the position to do that. However, in spite of the apology and the explanation, the offending words were repeatedly uttered by the guy as he was walking away louder and clearer than when he first blurted it out.

Suffice to say, that moment has been a defining moment for my boss. As for me, it has also defined how I value respect as a moral obligation.
