You can always say “I’ll do food running” if you do start fucking up during the interview. That’s how I got started, and I eventually worked up to server and then bartender and I have a moderate stutter that borders on severe if I’m really anxious. The thing about waiting tables is they want to see you can smile and are willing to work hard. Talk about how much people have always really liked you, and how your biggest strength is being “unique”. I got a bar job that way after stuttering a bit during the interview. Even if it’s a lie and you’ll be a shitty employee, act like you’ll devote your life to the place and it won’t matter how bad you stutter.
