As you begin to give the man some cash he grabs your wrist and begins to twist it. While you are shocked and unable to react he grabs the wallet out of your other hand in runaway. You try to run after him but lose him in the crowded subway station. You alert the nearest police officer and explain your situation. The officer says he will file a report. Do you follow him to the station or get on the next train and try to catch your flight?
