Typically Trini?

What does this mean? "Eats at the same restaurant every day"? I have never heard that as a Trinidadian thing to do. But, yeah, I do. So what? Is there something Trini about that?

Not that I would read NRO's corner, google took me there, but still...

HURRICANE ROGER [Rick Brookhiser]
Neither the Transit Workers' Union nor its leader Roger Toussaint has won many friends. The tabloids are on the warpath against them, but they are following the popular mood as much as shaping it. I'm hearing disgust in unexpected places: Ed Lover, the hip-hop radio host, was mocking Toussaint's accent. Out of the blue, my trainer called him a typical Trinnie (Trinidadian). "What do you mean by that?" I asked. "He's been here for years, but he still talks like a Trinnie; he probably eats in the same restaurant every day." (My trainer is from another island.)
Seems like New York is suffering from Hurricane Roger.
