With no offense to the smokers out there ... I smoked cigs for about 15 years (gave them up about 30 years ago) but I remember how I enjoyed it and how difficult it was to quit ... and I would hate to give up my 'golf course' cigar now, but that could be coming ...

SLM ... You might reduce the smoke effect by placing the fan close to you, blowing away from you ... I agree with kbrkr that any sign might offend the smokers, and possibly the management ... After all, YOU are the one who decided to work there ...
This is one of the hazards of 'club' work ...
When I work a smokey room, I usually hang my clothes in the garage when I get home ... then it's off to the dry cleaners ...
Fortunately, RI becomes the 7th smoke free state in the country next week ...
