Your Resume is going to go through an algorithm first before even getting to a human mostly likely since it was on a website. If you don't get an interview, I truly doubt it was because of you mentioning you have a stutter. You're going to have lots of chances to get a job, and chick-fil-a, while delicious, is just one of many like it. While I hope you get an interview, please do not blame yourself if you don't get called back. In the future, I wouldn't include it. I never have, and I never even mention mine in interview. However, Mine is very mild as I have learned (Never met another stutterer until College). If yours is one that is very noticeable, use it to your strength. You're going to be asked things about overcoming problems or solving problems - whatever the buisness-esque lingo they like to pretend actually matters at a fast food joint - so talk about living with your stutter and how you don't like it stop you from being an outgoing, cheerful, friendly person. It doesn't stop you from becoming part of a team or providing good customer service. My first job was at a Subway myself. Still love the smell! Good luck! You'll do fine.
