Nothing serious, but I took my car into my Audi dealership for service. They said it would take less than a day, so I left my prescription Raybans, my iPod and my gas credit cards in the car. It ended up taking several days, and when I came to pick it up all were missing. They acted as if it was no big deal, but I gave them an estimate of the value of everything they had taken and they reimbursed me.
Turns out there was a gang of car thieves in the area. The police caught them in a $50,000 stolen truck with a number of credit cards.
