Bull crap. And they also say the word "Jose" with the English 'j'.
either you are not in America, or you never met any Spanish speaker, or you are lying out of your teeth.
I would laugh if an American TV news reporters talk about the new Indian fighter Tejas, and of course, they will pronounce it as "Tehas" like any American would. And muse why would an Indian call their plane after the state of Texas. Or maybe he or she might thought they got it wrong and believe that the term "Indian fighter" means an American Indians boxer so the new fighter is actually an up and coming American Indian boxer with an initial of LCA is from the state of Texas.
