Nobody is more critical of another person's behavior than somebody who is very clearly The Problem themselves. It's the theme of just about every intervention, and almost all family therapy sessions.
A woman got a rude awakening when her one-star review of a bridal shop turned into an intervention of sorts. She complained about "cold and fake" staff shortening their alloted time, and insisting that she and her friend drink water and take an Uber. The reviewer insists that that was "uncalled for and unnecessary," but then the bridal shop told her side of the story.
