That's regular hood shyt. nikka just disrespecting the customer. That's really some amateur beginner drug dealer behavior. One thing about j's is that they always $2 short or trying to come to a nikka with like $7.89 in change trying to get a bag. He shouldn't have even let the nikka come short to owe him $2 in the first place, because if you stern on that no shorts shyt, they will go find that $2 and come back with all the money.
Then the fact that the j apparently threw the $2 at the nikka

means that he gets no respect on the block. Cause real talk, if nikkas really had any fear, that j would have took off running. They probably done shorted that nikka on the block so many times that he just got pinned up frustration from taking $7 for $10 bags and barely being able re up. Plus, he probably spend so much money on weed that he be short on re up. nikka probably getting fronted 7 grams of coke taking 3 weeks to sell that shyt so the nikka be on edge
