Its more of the long term status, if you spend a lot of time round smokers like you say, be it at home, in pubs, clubs etc. Not sure if you can compare it to hamburgers because if you eat one infront of someone it doesn't effect them at all.
But I do agree with your point on asking people saying you don't like inhaling their smoke.
