I go to my local B&M almost weekly, so they know me well and leave me to my own devices....I generally will purchase a smoke, take it into the backroom, shoot some pool or play some chess for an hour or 3, and head out until next time. Sundays are great for lounging with a smoke and watching my Patriots kick some ass, and cheering them on with 8 or 10 like minded folks....
I have gone to a couple of other locals(Concord N.H. has an abundance of cigar shops), and experienced the excessive input and scrutiny others have described...I very rarely return, unless I'm looking for something my regular shop doesn't carry regularly....if I do want something, and I can wait, I'll have my regular shop order them for me.
