Thanks for the explanation MtheGM and apologies for the misunderstanding.

I like the term 'defensive smokers', Charley. Conjours images of people defending their cigarettes in the time honoured tradition of huddling round the secrative dog-end with hands cupped to protect them from the aim of snipers:-) I think 'offensive smokers' may be nearer the mark (ref. snipers again) though!

Cheers
