Don’t fear it, but look at it as an opportunity to practice your speech and see better where your strengths and weaknesses are. You will get comfortable once you develop experience. Yes, there are shitty customers, some who feel bad once they realize you have a stutter and others that just don’t give a shit. There’s also plenty of people that are just clueless and many that are nice and patient. You will be speaking much more than you probably to do now to strangers and I personally find strangers to be the most challenging to speak fluently with, so it’s great for me to practice breathing and fluency. I’ve encountered numerous people that have stutters or used to stutter as well. I’ve never had issues with my employers or employees. They might get a bit frustrated sometimes thinking your fluency impacts your performance, which sometimes it can, but that’s what you’re working to improve and as long as you are trying their is nothing wrong. Try not to avoid customers because of your stutter (there’s other reasons not to talk to certain customers lol) My employers have never treated me differently because of my stutter. That would be very unprofessional and I wouldn’t work for someone like that.
