Sophia Sullivan, director of Summit Advertising, secured an 80 million deal. Her 88,800 expense report was thrown in her face by the boss's wife and finance director. Her boss reneged on covering costs, sidelining her, suspending commission. After resigning, she faced a non-compete and expense deductions. Sophia became a client, sending a formal letter. The 80 million partnership terminated, Summit Advertising audited, and her expense report paid. This became the most expensive lesson.
