What has opinion on smoking got to do with the job I applied for?

Then interviewer will think you "pandai pandai want to jawab balik" attitude. Its better to "buat bodoh" ask to test waters.

Ahhh you seem to have attended a lot of interviews. Sometimes cocky interviewer just need to be put where they belong. I remember my last job I really give the interviewer a good shelling. When it was my turn to ask question I gave him a tough question. His answer was "this only the management will know". I responded, "Gee, believe it or not if I ask any 7 years who just started school they will give me the same answer?" He was stunned as he did not expect an interviewee would dare to insult him. I spare no mercy, "Wanna put a wager on it? You pick the school and we go ask 10 Std 1 students there. *knock  knock on table* Hah, I don't think so. What's your position here by the way?" I walk off saying, "thanks I know my way out".
