In many ways, T&T’s alias, aka, is/was Texaco, Pointe–a-Pierre, and Petrotrin. So predominant has been the oil refinery in this land that it shared a nomenclature identity with the name Trinidad in much the same way as people going to America who often say they going to New York, even if their destination is actually New Jersey or somewhere else.

In my childhood days, it was common to hear that people were working Pointe-a Pierre or that so and so applied for a job at Pointe-a-Pierre. The ambition of those studying the sciences at high school was to get a job at Pointe-a-Pierre—meaning the oil company located there.
In the Southern sugarcane area, persons working at Caroni Ltd often said they were working Usine which is where the factory was at Ste Madeleine, but the location of Caroni became its identity as much as its corporate name.
