I do believe that his "agreement" is not official, and he believes that if 'kept in the closet' or under the umbrellas' that no one will kick up a fuss.
There is a CO beach in SXM it is also known as Club O.

You cannot have a 'hand shake agreement' to supersede a law.

Feel free to go CO at your own risk, if not at Orient Bay... Club O.

Just IMHO
