B--Right: Good Afternoon, can I help you find something sir? You probably didn't know that this is private property.
With me I am up and moving with A or B

IOW --- "A" is not a blow to my psyche. I just shrug and move on. But with others you have to walk on eggshells
This officer should have taken a good look at the man. Made note on his appearance. Does he look tired, drunk, high, ill, agitated, sleepy? How is he dressed? Does he appear to waiting for something or someone? That would be a good way to start a conversation with the man to find out what he's about.
I am thinking about the instances when cops have hurt or killed people with medical or mental conditions. Observation before confrontation.
