I got one for you. My old Sensei (Errol Lyn, Seido Karate Jamaica) too picked us a bunch of us to give us a ride to a small local tournament. We being kids wanted to stop for drinks and candy so he did at this gas station. Some guy saw it as an oppertunity, guy with his wife and abotu 10 kids in the van pulled a knife on him while Sensei Lyn was filling the tank. Let me just say, that was one of the most epic *** stompings I've ever seen!
