I was 16 when I got my first job at a juice store. I hated talking cause back then my stutter was really bad. At first I was stuck in the dish washing center, then I moved to another store where I picked up making and blending smoothies. I didn’t want to call out the names of the customer cause I stuttered really bad. My boss back then made me do it anyways. Guy was an asshole but a respectable one. I improved cause I had too. If you can do speech therapy, I would recommend it. Took me years to get as fluent as I am now. Don’t be scared. You can do it.
