Second-hand smoke: when you work in others' homes, where do their rights end and yours begin?

Abstract

First paragraph: Imagine someone walking into a cafe, sitting down at a table and lighting up a cigarette. In the UK – and other countries where smoking in indoor public places is banned – that would be almost unthinkable. In the 15 years since smoking bans came into effect across Britain, smoking inside has gone from a fact of life to an aberration, and the nation’s health is all the better for it.
