I have problems with seven too. And twenty. And zero. I can be successful if I get a running start at it ( your total is seventeen dollars) or if I prolong the S out a little longer than normal. Sometimes I just stutter and keep going. If someone says something sometimes I explain I’ve had a stutter since I was a child and sometimes I plow right past it. Keep in mind that if you listen to how “normal” people talk, everyone has disfluencies from time to time. We are hypercritical about our own speech and tend to beat ourselves up, making it worse. Eventually you get old enough to not care as much what other people think about you, and then you are free. Think of your job at domino’s as training for something better. You’re learning how to deal with yourself and other people. You can still do the things you dream of.
