I was sitting outside High Point Coffee on Union in Memphis today about 12:15 drinking coffee and reading a book. Behind me I heard some yelling all of a sudden. I turned and looked, and there was an obvious thug standing beside his car in the middle of the parking lot yelling obscenities at the cell phone store next to the coffee shop. That struck me as curious because the place was closed. Maybe someone was in there working or something but I never saw anyone. Anyway, I am now keeping an eye on the guy, and watch him reach into his car and pull out a length of pipe. He continued to yell threatening comments at the store and started walking towards it. This is when I stood up, grabbed my cell phone and was heading into the coffee shop. He looked over at me as I neared the front door holding my cell phone open. He immediately turned around, jumped into his car and drove off. As he drove off he yelled something at me I didn't catch. At no point did I remotely come close to feeling I had to draw my pistol, but the ole adrenalin really started to kick in. I wasn't able to get a tag number, so I didn't bother to call the police, but I did warn the employees at the coffee shop to keep an eye out for him and his car - a tan El Camino.
