In Grenada they say, "have a blessed day" when they say goodbye. The also say, "hello, good morning," "hello, good afternoon," etc when they greet you on the street or in a shop.
One that I think is interesting (I think it may be English of French) is their name for New Year's Eve — They call it Old Year's Night. I'm looking forward to Old Year's Night party on Hog Island.
The Christmas winds are going to die down next week and that will be great cause that is when I'm planning to sail off north.
