It varies, some smile, some smirk, some are a little confused. I’ve only had one person try to make fun of it but he was in handcuffs and strung out on drugs. What plays a big role is how you deal with it and carry on. If you make it a weakness others will see if that way. I literally just say when I’m having a hard time speaking “sorry I have an annoying stutter, anyways..” That way you owned it, they now understand what they are seeing, and you’ve broken the ice so there’s no reason to revisit it. Hope this helps!
