I had a temporary supervisor that used profanity a lot. One day he's deciding that I "needed" some counseling about a situation. The man has a PhD in Education, and likes to remind people of it. So he's going off on me, about the situation, and I'm tuning him out because of the profanity, and I finally said "If you're so f***ing educated why can't you express yourself without swearing? And if you're going to continue to swear, I'm leaving."

Stopped him in his tracks. He had been counseled before about his use of profanity in the work place (white collar job).

I have difficulty respecting a supervisor / manager that can't express themselves without swearing. Drop a brick on your foot, colorful language is probably appropriate, but in the work place it isn't.
