In the 19th century the words reliable and talented were singled out as being objectionable, because it was believed they were Americanisms. People are still railing against Americanisms in British English, as the author of this BBC piece describes. Well, some people rail against them, whilst others use them obliviously, not really understanding what they are saying. So, for instance, people in Britain will talk quite happily about stepping up to the plate, without having a clue about, or interest in, baseball.
The writer of the article notes how so many people use the American word now, even if a perfectly good British one exists: we go to watch a movie, not a film; we drive trucks, not lorries; we use the elevator, not the lift; and we live in apartments, not flats.
For more Americanisms that irritate some people over here, see the BBC article.
