Vanessa had been a waitress at Joe's Good Eats for seven years. There had always been differences between Vanessa and Joe because they had radically different views on politics, religion, and sports, but he had always overlooked these differences because he liked her and she was a good waitress. However, one busy day with the restaurant full of customers, he began ranting about city politics. Vanessa whispered, "Please, Joe, you know I don't agree." It ended with Joe yelling, "I've had it with your radical ideas. Get out!" So Vanessa left. The employees at Joe's were not unionized.
