Also, I notice you didn’t make him stutter much?
It sure does takes a long time to write his dialogue but that way it seems more in character but it’s fine if you choose not to.
It’s your own story after all.
One more thing. If you choose to write his stutter, don’t write to them like ”th-the-these”. Trust me, I felt so embarrassed re-reading my old stories after all these years.
Instead, write them like these,
”Hav, Have a goo, good day, Sir”
It’s probably not 100% accurate but I think this way sound way better.
People who stutter don't really stutter on each word and them more likely to have pauses between words and have a hard time pronouncing some longer words like good, hood, and etc.
