Hi teacher. The following sentence is from movie " Thank You for Smoking ". I don't understand the connotation of "vending machine world " and how he came from the vending machine world could make him tough.
B : Everyone has a boss. "BR" just happens to be mine.He came from the vending machine world.This made him tough.The name "BR" came from his tour in Vietnam. The people who know its meaning are all dead.
As to its use here, I take it to mean that he started out as a salesman for vending machines.
