The People's Republic Of Maryland no longer allows smoking of any kind in a bar or restaurant; but when it did, I recall a couple places here in Baltimore that had signs, "no pipe or cigar smoking", which I thought was pretty crazy.
This is a weird story, and I actually wrote a song about it that I've recorded called "The Who Goes There of All Who Go". There was this one downtown bar I was in back in the mid 90's that had no sign about cigars, but I was smoking a Dutch Treat little cigar I think, and this door man who looked like a character out of a Charles Dickens book, with a black top hat long coat, and long hair sniffed it out (it was a crowded Saturday night, and the place was filled with people smoking). He comes up to me at the bar and asks me what I'm smoking. I reply, then he tells me, "the woman who owns this place is allergic to cigar smoke, so you can't smoke that in here." I said OK and promptly put it out. Then he did this real pretentious thing where he put his fingers to his lips like he was smoking in a cigarette and said something like, "in this bar we're of the cigarette", which I used for a line in the song.
My bandmate sitting next to me shared his pack of Marlboros with me (I still smoked cigs back then) and said "that's bull#%*#; I know the lady he is talking about and she is like 90 years old and hasn't set foot in this place in 20 years". His theory was that around this time is when the whole cigar thing was getting real hot and trendy and there were "cigar bars" popping up downtown, and this place which was kind of a pretentious artsy, fartsy hangout didn't want to be associated with all that.
