How did Clarence know how much the drugs were worth?
Clarence (unwittingly) steals a suitcase full of coke. Later in the movie, he shows it to his friend Dick and asks Dick if he can line up buyers. With assured confidence, Clarence declares he is selling "a half million dollars of white for 200 grand."
It begs the question, how did Clarence know the coke was "worth" 500K? As far as we know, Clarence is not a drug dealer. So how does he arrive at the 500K figure when declaring the drugs' value? Was this lazy writing? Did I miss something?
