Mark: Look, lady, I've been waiting three hours! Woman: I'm sorry. You didn't have an appointment to see the president. Mark: An appointment!? Are you crazy, lady? I'm here to take over his office! Woman: Don't shout at me, buster! I'm just doing my job! You don't have an appointment, so you wait! Mark: I've got to get out of this business.
