I was taken aback by the aggressive posture the 5 foot 3 man took when I told him I could not sell the item for the price he asked. He was unaware that I had a bat under the counter that I had wrapped my fingers around. Suddenly, he took a lunge for me over the table and I was able to move just before he grabbed my jacket. I immediately brought the bat into both hands and could tell that this caught him by surprise. Unexpectantly, a young man came up behind the attacker and wrestled him to the ground which he did quite easily. I decided at this point I wasn’t going to hit him with the bat and helped keep the man pinned down until law-enforcement officials arrived.
