Here is the missing piece of the tale: why did the manager want the parking lot swept? I've been in a shitload of positions where I was assigned menial tasks for a variety of reasons. In some of those. positions I could say no without drama, in some I could quit, in some I could say "Yes sir/ma'am", in some I could delegate, in some I could outsource. In every case, I could respectfully and tactfully ask why. "Is there any specific area that needs extra attention?" "Will somebody else be covering my standard duties while I do this?" "Is this going to be part of my regular duties or is this just to keep me busy?" ... and so on. Tone matters depending on the relationship you have with the manager. But a violent reactive act and profanity doesn't seem like the best way regardless of how righteous you feel years down the road. I wouldn't hire you if this was your "tell me about a time you dealt with adversity in the workplace" interview answer, that's for sure.
