It's about mixing'em up! Not the coffee, because we only bring you single-origins. We're talking about languages.
In Obura-Wonenara (and across Papua New Guinea), slowly, the Tok Pisin is crowding out the other dialects and becoming the primary language.
Tok Pisin can be freely translated as Talk Pidgin, and this says a lot about the anthropological history of PNG, a country with hundreds of indigenous populations (that are often very distinct from one another in terms of custom and language), that had German and British colonies during the 19th century. Those factors make communication and the cultural sensitivity required to do business there more difficult than in any other coffee-growing region. The language draws vocabulary from English, German, Malay, Portuguese and local Austronesian languages.
(Have you ever had an introductory linguistics class at Starbucks?!? I don't think so.)
