Funny, same thing happened to me in the regards to receiving too much green. Idk I knew I'd never go to him again but when he called I felt compelled to turn about and give him the extra 10.....You don't have to but either he will A) Call you non stop until he makes a visit to you or he will B) forget about it and spread the word to any other dealers he knows that you don't pay. Either way your going to get your ass kicked if you ever run into him on the street I think thats the only constant in both situations. .....Was it good green, seeing all the problems said sack gave you?
