I was visiting UK, and somebody asked me, "Where do you ....?", which I couldn't understand.
The last word sounded like 'biased'? 'baist'? 'by at'? 'by ast'? something like that...
And, he noticed that I didn't get it, so he changed his words, "where do you work?" So, I guess the first sentence was also asking where I was working. Any guess for the last word that I couldn't understand?
