Well you dont have to limit your expressions and you can say whatever you want for eg; if a person says " can i get a burger and a coke" and he start to stutter at the letter 'B' of burger so instead of getting out the word burger at the end of the stutter, he can just say " can i get a coke and a burger". It helped me alot and nowadays some friends who are not that close in my life doesnt even know that i stutter. And yes there are some words that you cant ignore but its just a person has to play with whatever cards he got. I dont think that a person can ever recover fully from stutter but by watching his stutter or by carefully studying it many things can happen in a positive way.
