OK, you win; so there were a few cruise ships coming to the island by 1978, but there were not remotely as many as now. I don't think any of the piers were built yet, but you will set the record straight, I am sure. As you correctly said, I do not remember if there was anything at that corner or not. Other than that, my account is accurate; I am not making any of it up.Those are all nice memories, but as with all memories, there are some things that don’t fit the reality of the past. It happens to everyone; I am not picking on you. I much prefer researching old documents written at the time of the event or looking at photographs to interviewing folks about their memories for just that reason.
BTW, Google Earth street view clearly shows the Rasta's sign on the place across the road from the bar I was speaking of, i.e., what was at one time Bob's Marley Bar, aka Paradise Cafe; the image is not taken from close enough to clearly show any signage on that place.
EDIT: I just looked at some video I shot there in April; I was looking for a sign on the bar on the water side of the road. I didn't see one in my video but the menu on the wall says Rasta's as well.
