Yeah, ordering food and stuff always made me nervous too. When I would go out to eat with friends or family I would always look for something to eat that was easy for me to say instead of getting what looked good. Saying certain words before I say the food I want helps me a lot. Like saying " i want the chicken wrap" the word "the" helps me say chicken. That has helped me. Idk what helps everyone else but the biggest thing that helps me is just my mental well being.
