I used to have a dealer who didnt even use a scale. He would have me meet him in some random parking lot and then pull out a big zip lock baggie and give me some nugs. It was usually only a dub so there wasnt much point being too much of an ass about weight but usually I got more if I bought by dimes, I just didnt like calling him all the time. But he barely ever had bags and would usually give me an extra nug for the inconvience.
