How does biff react when he realizes that bill oliver doesn't recognize him?

Answer 1

One of Biff's old employers. Biff believes he was a salesman for Oliver a long time ago, but he quit because Oliver suspected that he stole a carton of basketballs. When he left, Biff claims that Oliver told him to come see him if he ever needed anything, and so years later, Biff expects that Oliver will loan him ten thousand dollars to start a sporting goods store. When Biff meets with him, Oliver doesn't even remember Biff because Biff was only a shipping clerk, and Biff, unable to control himself, steals Oliver's fountain pen and runs out of the office. It is this moment that makes him realize his whole life has been a fraud.
