Great story, thanks for posting.
A few years ago I drove dad (6' @ 175#) then 84 to a supermarket in a "bad" section of town and I waited in his car by the sidewalk (some special sale and mom had to have something). Some big black guy approached him shook his hand, would not let it go and "asked" for money. I get out of the car and as I approach I here dad who is staring straight into this dudes eyes, say, in a very direct deep voice, "I ain't afraid of no man". The guy who never saw me coming up from behind immediately lets go and says "sorry, have a nice day sir". Go pops!
