Have an interview in 3 hours and I’m nervous/excited.

Have an interview in 3 hours and I’m nervous/excited. I’m applying for a spa attendant position for Gene Juarez spa and salon. I really want the job but am a littler nervous my stutter will get in the way. I put on my cover letter than while I may have a stutter, it does not hinder me from being outgoing and from talking to people (which is true but it’s still hard). This way they are aware of my stutter and won’t be surprised about it when I start talking. Hopefully all goes well!
