Like any other social situation, depends on the context. In casual settings, I usually just roll with it and don't acknowledge it more than I have to. If I meet someone in a social setting and they give me a hard time about it, they lose my respect and without really thinking about it, my voice takes on a more curt tone, which forces a bit more annunciation and has a similar effect to speaking with an accent, in that I tend to stutter less. In more formal professional settings, like a presentation or making a comment in a big meeting, I power through what I have to say, blocks and all, then follow up with an acknowledgement that I stutter to diffuse any tension, real or perceived. I'm a nurse so I speak with patients one on one all day too - I'll acknowledge it if it's really bad, because I want them to have confidence in what I'm saying to them, but otherwise treat it like I'm just meeting anyone else for the first time. It's way easier said than done, and I don't always feel this way, but I always try to remember that what I have to say is valid, and anyone that thinks lesser of me because of my stutter isn't worth my time, whether it be a prospective employer or co-worker, a date, or the person who has to suffer through listening to me order a steak and cheese with hots and barbecue sauce. I know how I want my sandwich and they just have to deal with it, dammit.
