Currently work for an energy company. I found it scary as fuck at first and nearly quit but that motivated me to do well. I find ways around my speech, and even after nearly 6 years I still have hiccups and moments but it doesn't bother me as much. Sometimes I have to tell customers but not very often, maybe once a year or something if I'm having a really terrible day speaking. - I find most people don't even notice, and if they do they don't care, so I don't.
