Unfortunately if you shake hands they will hold on for dear life while they try and sell you something (literally hold onto you kinda assault like).

The last few years it seems like the higglers start with "buy this? buy this? buy this?" and when you don't they ask for 'support', basically begging. I know countless couples who will never step foot in Jamaica again due to the non-stop high pressure hustlers.

Be polite but don't bother offering a hand, hug, or fistbump unless you want to hear their bull****. Or worse, have to pry yourself from their hold.
