I worked at a job where for some reason my stutter got triggered constantly. Mainly, on the phone. It was terrible. Ever since I’ve been scared of the phone 🤣 As I get older I try to remind myself confidence is KEY. Even if you stumble, if you’re confident it seems to get better. Maybe practice with someone? Or practice on your own speaking the name of the business in different tones, maybe there’s a word you can say just before hand that would make it easier? But I definitely feel your pain. Same thing happens to me.
