"Oh, sorry, I thought this was <neighbouring store>", backpedal (not turning around), get behind cover (not the getaway car), scan, draw, call the cops (stay on the phone, give your description, describe the BG).
If he comes out and starts shooting, it is he who started the fight in the street.
You may use lethal force to save someone elses life, but you don't have to insert yourself into an unclear situation unless you are a cop. I also assume that there is some kind of doorbell so the BG does see you first.
