What should I do if the operations foreman in the company that I worked for wanted to fight me (a regular employee)?

A is the operations foreman and B is my immediate foreman. I was standing by a muscle cart with sandbags stacked on it that had been pulled for an order the night before. I saw some electrical tape on the handle and started taking it off as A and B were walking towards me. B asked, "Who pulled the order?" I answered, "A co-worker and I did." I am not sure if B was in the middle of saying something, but A interjected and asked about the tape. I said, "I was going to pull it off." Then A asked, "Do you send cable out with tape on it?" I responded, "Sometimes we do." He said, "Stop being a smart ass, I'm just asking because it shouldn't be put away that way." I said, "Sometimes we are told to put it away with tape on it, and sometimes we are told to leave it on after we pull it." A then stormed off and as he was walking away said, "If it keeps up this way then you're going to find yourself unemployed. I responded, "Then fire me." A then turned around and yelled, "Get the out then, leave!" I turned around and started walking towards the punch clock. I don't recall what A said but I responded, "I'm sick of your little fits." I don't remember if anything was said after that but A turned around, started taking his coat off, threw it on the floor and started coming towards me with his arms up asking, "Are you still on the clock?" I said, "Yes." He then told me to clock out like he wanted to fight me. I stopped where I was at, put my arms down and told him to hit me. He told me to clock out again, and I told him to hit me again. This happened two or three times before I turned around to go clock out. As I started walking away from A he called me a pussy, which proves that he wanted to fight me.
