I think a lot of Jamaicans have caught on to the Tan Booth...they still can tell if you are new.....remember this is a "small" neighborhood...and they are looking at tourists all day long...they see a fresh one, just as if someone moved into your neighborhood, you would notice......
it does help you with the sun so you wont get fried the first day, hopefully
Just say No Thanks...dont say "later" or they will press you further for when??
if they persist.."NO I DONT DO DRUGS" spoken very clear and LOUD, will get them movin on....also callin you all kinna names lol
the last thing they want is a loud voice, that might attract attention, or competition
they can be enjoyable, and you may make a "true" friend that will last for years, we did many times
