Stranger Savior!
I used the drive-up ATM at my bank, got my cash and drive off. The car behind me pulled up to the machine, paused, but didn’t stay there and followed me.
He followed for a few minutes. At a stoplight, he walked up to my car and handed my bank card back.
Bro could have cleaned out my account since the card was still in the machine waiting for the next instruction.
No clue who he was. I barely understood what happened then he was gone.
