CaptainD answered this very well..
It isn't the question, but the questioner. These rules apply no matter what city or country you are in.
If I was in Negril and a beach higgler approached me while walking the beach and asked the questions, my answers would be vague.
If Clarol working the bar at Seastar Inn asked me where I was going and when I was coming back as I was heading to the gate, I wouldn't hesitate to answer her.
Enjoy,
