Twice. When I went to get my oil changed, the worker stuttered and I was happy in a way of like happy for him to be able to work in a social job despite his stutter. I didn’t tell him that though because at that time I was embarrassed of my stutter so I kept things short. Another time when I was working at my retail job and a guy who stuttered pretty much whenever he talked. Idk how to explain it but he stuttered more than he talked but I kept reassuring him to take his time because he was talking fast.
