In NZ the question "where are you from" is often a short hand for "where did you emigrate from" since we have such a high proportion of immigrants in the population (especially in Auckland). I am one myself.
But not always. So when I am asked the question, I don't try to be a smart ass, I simply cover the bases:
- I'm from Auckland, but originally from the UK.
That gives enough information for the other party to the pursue which line of inquiry was actually their intent... "Ohm where in Auckland?" or "Oh, where in the UK?", and we take our cordial conversation from there.
Maybe you didn't think that your service droid should be asking those questions or needed to know the answers, but in that case just goddamed well say so: "I'm sorry, I'm not comfortable discussing that with you, if you don't mind.". On the other hand, whether you thought it was any of their business or not, what possible harm did it do the world for this service droid to attempt to - presumably - make your day a little more human and a little less transactional.
Being intentionally difficult (I am sure you understood perfectly well what their inquiry was driving at) was not a very mature response.
As for Eliot Chang.... he calls himself a comedian. Is he supposed to be funny ?
