To put a foreign object in restaurant food and file a complaint. From the Wendy's incident in which Anna Ayala claimed to have found a finger in the chili and sued. It turned out her husband's coworker lost a finger in an accident, and gave the missing digit to Anna. She got 9 years in prison for fraud.
When I went on one of my big bike rides, I decided to stop for lunch. I saw someone put some unidentifiable object in a carton of fries and made a scene. I thought, "what an Anna Ayala"!
