So I had a situation tonight which has shaken me up quite bad and people think this is fake or whatever as I've seen these types of threads been accused of it but whatever. Tonight I was out for a meal with my kids at a small place nothing flashy just a cafe. But I went to the toilets and nt long after I went in another guy entered he was talkinh to himself and seemed edgy and jumpy. I went to leave and the guy got in front of me and asked if I had a lighter, I politely told him I didn't but he refused to move and got angry yelling and swearing at me saying I was a liar and out to get him, obviously the guy was off his head on drugs or something. I simply asked him to move out the way then he refused so I tried to push past him and he yelled your going no where and he grabbed hold of my wrist. At that point pure instinct took over. For any kenpo guys reading I basically used the technique gripping talon. It's hard to explain but I twisted my wrist and basically got his fingers in a lock position which made him go up on his toes in pain then dropped a right hammer fist to his groin which buckled him slightly. I used that moment to push him to the side so I could get out. I ran out and told the staff in the cafe and told them to call the police and gave my number to them to give to the police to come talk to me as I had no intention to stick around while that guy was still around so me and my kids left quickly. Later on the police called and I went down and gave a statement. They knew who the guy was and was a known drug user who'd often got violent. That was the first time I've ever had to use my training for real life and it has shaken me a bit even though I was able to do it successfully. Also I'm surprised I used that particular technique in instinct as its not one I like and honestly not one I train that often. I know other wrist grab defences which I'm way better at but I guess when instinct takes over anything can happen.
