I've yet to meet a smoker who has made any such comment.
As a smoker I do claim it is the choice of the PRIVATE property owner to determine his/her clientele.
I don't enter establishments that have raw shrimp in close proximity to the clientele. I can't handle it. I love shrimp and it is consumed on a regular basis in this household. But, I have to leave when my husband is cleaning it. I guess I'm entitled to push for a state law forbidding the presence of raw shrimp in any "public" place.
