To be honest that's a tough call. It would depend on the area I was in. Smart thing to do would be to call the cops and wait in the car until they arrived to straighten things out. 30 years ago was a different time and place than today. It was the norm for people to help each other out. The use of a rouse to rob someone was uncommon if at all. If I was a city today no way would I open myself up to that kind of threat. A rural small town, thats another story; there are a whole host of factors to take into account.
