I had a home meet and greet for a possible housesitting job around Christmas. The problem is the owners smoke inside, and after about half an hour, I smelled strongly of smoke. I have a lot of health issues that are exacerbated by cigarette smoke. There's no way I can housesit and not harm my health. How do I politely decline? I'm afraid it will sound like, "Ew your house smells" if I'm upfront about it. I don't want to make her think she has a sitter and then bail on her. Thanks for the advice!
