Okay so today i was performing for a group of people and among them there happened to be someone who was learning card tricks, i wouldn't call it learning, he only knows a couple of moves like some forces and what a Double Lift is. He kept on calling all the moves i was doing like a rifle force, a DL etc. But when it comes to more complicated tricks, he was quiet. He also said that if i did it one more time, he would catch me. I was really pissed off and just walked away. So my question is , what do you do when you are in this type of situation ?
