Thankfully, no- but came close three times. The first time several years back, a couple of thugs approached me menacingly when I was walking near Georgia Tech campus. While I normally keep my weapon very concealed, one of them spotted a portion of it when they got within about 12-15 feet, and they immediately turned and went the other direction. About three years ago someone approached my car door in downtown Atlanta. I saw him approaching, so I placed my weapon on the seat next to me in plain sight. Once he saw my weapon on the seat, he moved quickly away. About two months ago I was in a local Wal-Mart when a BIG black guy tried to push his way in front of me in the self-check out line, talking smack and trying to impress his family. I stood my ground as he screamed inches from my face what he planned to do to me, threatening physical harm. No one from Wal-Mart did anything to intervene, and everyone within ear shot stopped to watch, while those closest moved quickly away. I calmly told him that he would have to wait his turn just like everyone else and continued to scan the rest of my items (the ones still remaining after he threw some of them two aisles away). I half expected him to follow me outside. I never even hinted that I was carrying, but I took great comfort in knowing that I could protect myself if he tried to do something really stupid.
What a loser. He threw your stuff?
