Not me, but my boss - was flying home to JAX from DFW. At security, apparently the woman in front of him accidentally picked up his briefcase, which was similar enough to hers (the one she left behind) that he picked hers up and didn't notice until a couple of hours later.
He looked through bag and found her laptop and contact information (in Brazil). He contacted her directly (rather than going through our corporate security) and arranged to cross-ship the laptops which were in each bag. She was super embarrassed and apologetic about grabbing the wrong bag. Neither was very concerned about getting the briefcase back, but obviously the laptops were a big thing.
So he went down to FedEx Monday morning and overnighted her laptop to her.
And she didn't.
So now she has two.
