Eerily similar to a situation I found myself in last week. Leaving the hospital, visiting my dad after he had surgery, an individual in a remote parking lot was being very insistent about getting a ride. I was carrying concealed, and while I did not full on draw, I was on about halfway. (never fully drew my pistol) He was, best I can tell alone, as I checked the area I quit hearing the words come out of his mouth. Not sure if he registered what my motion was, but decided to go look somewhere else for a "ride".
I suspect Ill get hollered at for brandishing or what have you, but after fact armchair criticism doesn't hurt as much as a thump in the bean by someone potentially willing to do a guy harm.
