^Well if he wants to make money he probably will.

Think about this.
Who gets paid more?
-The drug dealer who cheats a client, (steals a guys money without giving him the product).
Or
-The drug dealer that gives that client what he wants?

Answer:
Both make the same amount of money...on that day.
But! The client is more likely to go back tomorrow to the second dealer (the one that came through with the product). Also, he/she is more likely to tell his or her friends about how the dealer doesn't jip people.

So who is going to make the most money in the end? The dealer who rips off people, or the one that doesn't?
