i just had a brainstorm......tell a friend to guy buy 30 worth the weed from him ( afriend you can trust) and tell him to tell the dude that he needs the weed upfront cuz he's heard some rumors about him just taking the money and then tell him to take the drugs and fuckin run.....you get the weed from him and then everythings fair with no violence and then just don't deal with this dude anymore.
