when i delieverd to people, they usually would always smoke me up on a L or throw me some extra bucks.. i mean the best thing, in a dealers eyes, (i think most people can agree if they do) that the respect you get from doing mature and well buisness is better than alot of things that could be offered and with this respect the growth of ur buisness, reputation, and customers and the fact that hopefully this customer will keep coming back for the goods?? thats just my personal opinions from experience.. another thing is that you make alot of friends doing it and good friends at that... just be courteous and if u want to throw him/her something extra, do it if not no offense would be taken..
