The Doorbell Calls and I'm in a Medical Office and I Need a Ride Home

A 21-year-old woman says she was approached by a strange man at work. He said he needed a ride home and asked her to pay for an Uber, which she did. The next day the same man showed up with his car keys in his hands. She called police but they couldn't do anything because it was so threatening. After making a report through Lyft I haven't heard from him again.
