I used to work at Starbucks, when i was hired i was hoping that because of my stutter they would put me mostly making drinks however i was shifted to all positions. In the beginning it was tough, I hated speaking but since there was a script to follow (Saying hi, what can i get started for you?). It made me interact with people and tons of them it got me out of my comfort zone and working there you would get regulars who you can banter with. Eventually I felt pretty confident in speaking with people. Id look into getting a retail job like a barista, you're gonna stutter but you just gotta accept it and try not to let it get the best of you.
