I think sometimes when people call a salary offer "insulting", they really mean the offer is disappointing, worrying, and/or a threat to their sense of value vs. other professionals.

So I think there's value in reflecting why some job offer felt insulting. It may help the person recognize some thoughts or worries that were lurking in his mind.

On a less touchy-feely level, getting an "insulting" job offer can be a useful data point regarding the state of the job market, and/or that particular employer.
