Yea I hate it when that stuff happens. Remember though because weed is illegal, unfortunately you'll have to deal with crackhead dealers sometimes. but using a blade isnt going to solve the problem. potheads dont use violence to get what they want, nor do they steal. at least i dont and I have smoked the best weed in the world countless times.

if it ever happens again, just politely leave. i'm sure you can go a day without weed. just always be careful who you deal with. you never know when a cracker may try to rob you for crack money. i would laugh my ass off though if he tried to steal your money for weed. i would also consider him a retard too because you can never get addicted to weed plain and simple.
