I have a game I play with some of them...this is a daytime-only deal though....and was in fact suggested to me by someone on this board...it kind of sets higglers off balance...and evens the playing field!
Ex:
Higgler
"Hey mon, they yell, hey mon come here!...smoke/etc?"
Me:
"Nah, I'm set but...heyyy! Remember me?"
Higgler:
"Yeh mon! Yeh mon!"
Me:
"What's my name?
Higgler:
pregnant pause/
"Uhhh..Bob/etc?"
Me:
"Ha..gothca! We never met bro!"
This inevitably sets them off guard, gets a laugh, and then I chat and say "respect" with perhaps a fist-bump. I also let them know I'll be sure to let THEM know if I want anything, for sure, no need to ask me, I'm set. Saves the whole routine next time.
Back to the whole "the beach walk is an experience" idea.
Oh: and I come to Negril a lot, like 5-6 times a year and I've been here two weeks, leaving in a month etc. (Anything but the truth)....
