This happened on the Tube. I exited a train and was standing on the platform. A stylish lady left the train and started walking away. Suddenly a young woman ran after her, holding a fedora, shouting, “Excuse me, you forgot your hat!” The lady turned to her and replied, “That’s not mine, I think it’s that gentleman’s!” The young woman turned to the train, only to see the doors close as the train started moving. In the window, a man was staring at her with a look of disbelief on his face. The end.
