Most likely Dave has already got a life and he is trying to hang on to it
and his health by avoiding passive smoking.

Presumably you are a cancerous vulgarious, otherwise you would appreciate
just how abhorrent the putrid stench of second-hand tobacco smoke is to
others.
Actually there are some areas where ground and location mean that the
smoke and smell lingers far longer than is normal. You sometimes get in
in areas around offices when people are accustomed to smoke . You seem
to get a sudden blast of it as you walk through the area. Maybe the OP's
garden is such an area.

Cook curry or burn lots of toast is my only other advice
