It is hard to convince the everyday Jamaican that being nice and not pushy will get you more over time than aggressive tactics. Kind of like new and used car salesmen and telemarketers, if you score once out of ten tries you are successful. When people are poor and their bellies are not full they are acting more out of desperation.
You don't find this attitude as much out on the island away from tourist destinations even though they are just as hungry and just as poor.
