The job is not finished when the boat comes back and the fish is unloaded. This is only when the most tedious part of the fishing business starts : mending the nets.
I tried to speak small malay talk with the fishermen in Langkawi and though I reckon my bahasa is very poor, survival level, none of them seemed to even understand a simple "hello", I was really worried until someone told me that in this part of northern Malaysia, the simple people speak thai originated dialects.
