I could care less if a woman is in the lounge or not as long as she doesn't expect me to be any different than I am when it's all guys or feels she should be treated differently because she's a woman. The language is going to remain coarse (okay, foul), the sports are going to stay on the TV, the scotch will flow and I'm still going to be just as opinonated as I am. If she can handle it, she's free to jump on in and hang out. Can't handle it? Don't know what to tell ya other than, "Bye and have a nice day."
One of our cigar reps is a woman and she can hang with the guys pretty well and probably better than some of the guys.
