an answer with a twist... when he turns to walk away... if you have some sort of problem with shooting someone in the back, draw your weapon, and say "hey" as he turns around give him the "copper washing".

and it goes without saying that if a guy with a drawn gun gets within 60 yards of you, without you noticing... something else has gone wrong on your part.

if he gets within 50 feet of you without you addressing him, ready for action, then you have failed, and if at any distance he goes for his waistband without you out-drawing him and hitting him before he hits you, then you have got to get more trigger time, and i do not mean at the local nanny gun range with their "no drawing from holsters" nonsense. you might have to drive a ways... but go somewhere where you can REALLY train.
