As an ex-smoker I know I can be a bit anti-smoking, but purely from a health point of view.
I don't care if people want to smoke when they're not looking after my child but when I pick my dd up the room manager smells like an ashtray and it's unpleasant and unhealthy.
Am I being unreasonable or justified in wanting her to wash her hands and change her jumper after she's had a fag?
