Murderer in the Back Seat
This was one of the legendary horror stories featured in the film “Urban Legend” in 1998. A woman pulled into a gas station and was frightened by the strange behavior of the service guy, who kept trying to convince her to get off her car and come with him to the office. She refused to leave the car and sped off instead, not knowing that the attendant had glimpsed a knife-wielding man in the backseat and was trying to save her life!
