same shit happened to me! i was sitting in my garden having a few tokes with some friends and i seen a group of lads walking past i knew one of them dealt but never got shit off him before so i shouted over ANY SMOKE? and sure enough he did i got a half oz off him was handing him the money and he snatched more than i was giving and tried run "these fuckers are known as total scumbags" so i managed to get my stoned ass off the comfy chair i was sitting on and ran after him and bet him silly and took all his weed and my money back! never let anyone steal from you at your own place!
