Ever been scammed buying drugs?

Ok, so this isnt realy a question. I just wanted to hear other stories (Fact, or Fiction) of people getting scammed trying to buy Marijuana. I recently aka. 2 hours ago, got scammed trying to buy pot at Washington Sq. Park in NYC. Its not the most reliable place but I have gotten sum decent deals, like an 1/8 of Cali Kush for $50. Anyways I was really high and thought to myself, "I'll need more bud for tomorow, my dealers sleeping so why not buy sum from the Park". I go over there and im still Blitzed out of my mind, when I finally find a guy who asks me how much I need. I ask for a 30 piece and the guy comes back with a folded up paper (all dealers at this park do this) and hands it over to me. I stupidly dont even look inside and continue to give him the $30, walking off with a pile of dirt in my pocket. Ive been a stoner for about 2 or 3 years, and I feel like this definitely hurt my personal ego as a pothead. Anyone else have any similar stories to tell that would make me feel less of a loser?
