I second everyone who suggested you disclose it before the interview! I started doing it a few years ago and I think it really improved my job interviews outcomes! And definitely don't apologize for it!! I say something like this, "Before we start the interview, I want to disclose I have a stutter". You can also add something like "it never prevented me from being successful in my previous hospitality jobs". I find that when I disclose, the vibe often shifts completely, it feels like people view you more favourably and you just have more power that way. I stutter way less that way too. I also think that a lot of people out there either never interacted with someone with a stutter or never gave it much thought. So, when they hear your stutter first (if you do not disclose), they just might get confused and try to figure out what's going on and that will distract them from listening to you. They might also feel bad about themselves for judging you and that can also prevent them from calling you back. Even if they feel like they fucked up, people don't like feeling bad about themselves haha. However, if you tell them upfront, they actually have an opportunity to be a better person by being supportive towards you!
