Petty crimes, such as pick-pocketing and street hustling, do occasionally occur. Care should be taken against thieves or hustlers in crowded places, like tourist areas, discos, bars and theaters. Avoid carrying excessive sums of money with you (or wear a secure money belt if you do), try to avoid wearing showy jewelry, and keep an eye on any expensive items, like cameras. Always try to avoid leaving valuables in your luggage, especially in hotel rooms or airports.
Also, recognize that hustlers on the street offering unbelievably cheap rum and cigars are not to be trusted, as their goods are often of lesser quality.
