It never occurred to me until my American born, 12-year-old niece wondered why I say the word “cheers” so often, and that I do. Until I find star-comedian Ricky Gervais doing the same on screen, probably after every sentence.

Assuming then it’s a British thing. And Bombay/desi English, in any case, is mostly a mix of British, American, and wherever else that you can make a bhel puri from.
