try to get some color the first few days, lessens that "new white look".......buy wrist bands and jewelry first couple of days...good "shark" repellant...lol........
remember not all Jamaicans understand American slang....like the guy who just wanted to give the change as a tip....."Tourist kept saying, thats ok...when she was giving change...she looked at him each time he said it...finally she replied "I know its OK"......so say what you mean.."The change is for you"........
its not a "Drug Store, but a Pharmacy......and not "Coke" but Coke a Cola or "soft drink" ....you dont want your "wants" to be mis-construed....
Always know the currency that you are dealing in...Is it 100.00 Jamaican or 100.00 US????????...some will flop back and forth between the two, its easy to get overwhelmed and confused and agree to something you didn't really want.......
Be nice........ your a visitor.....but dont overlook rudeness or improper behavior.......being a Tourist is good..it offers some sort of "protection" as a LOUD voice on your part will carry a long way....Speak UP you will be listened to............
HAVE FUN...most of all
