If I lit my cigar after they arrived, I'd be willing to move to a spot where no one was offended, assuming I could find one.
If my cigar was already lit when they arrived, they had every opportunity to pick a spot elsewhere. Might not be the politically correct andwer, but at that point, they are making the choice of where to sit.
