I'm surprised you were only hounded by three people.
I spent about a month in Negril, and you couldn't turn around without somebody stalking you.
One dude followed us into a grocery store and insisted on "helping" us shop. I told the guy to piss off about 28 times, but he wouldn't go away. Then he demanded payment for his help since we "hired him".

Yeah, right, like that's going to happen. Another guy followed us around while we were on scooters, trying to give us a "guided tour" we didn't want. We finally ditched him Starsky and Hutch style, in traffic.
Negril was just a constant barrage of scammers. I couldn't wait to get the fuck out of there, and I was being PAID to be there.
