Much talk about the way Jamaicans treat Tousists, could the way you treat them be the problem?
My Sister Denise is one of the friendliest people I know, when she first started coming to Jamaica with me, I realised her Hellos were not always being returned and at first being the big Sis I got an attitude at what I perceived as ill mannered treatment, but later realised they, the Jamaican women were surprised, at the 'evil, mean spirited'black American woman smiling and speaking to them, we found out later, this was the perception of us the Jamaican women had courtesy of thier men who were trying to keep the two groups seperated so that each group would be none the wiser..... Eventually the truth came out.
Over time I've heard some not so nice things directed at women who come into an area and totally ignore all except the guy they came with. Many use the mantra, what goes on in Jamaica stays in Jamaica for some this is just an excuse to be loose.
People watch and discuss you wherever you go and making people feel you think they are beneath you, can get your feeings hurt many times.
