haha, i just thought i had to throw that out here, to show how different it can be:
The scag dealer that i used to hook up with was one of the higher class buisnessmans (black), wearing a Tuxedo and driving a BMW, doing house-delivery for his regulars. He seemed like what i would call a really respectable guy. You gave him a call, he did not drop whatever he was doing, but he told you he could be there in like 2 hours or so, if that would be okay for you. If you said yes, he was there in 2 hours, never a second late, always friendly and a gentleman when it came to owing money.
The day i told him i wanna get clean he stopped selling me, not like the other usuals, and offered me 4mg subs for 2$ a piece or methadone for free.
All OC dealers i have ever met though, were shady people, standing at the corner, and you never knew where to find them. They never answered their cell phone either.
