Stuttering at work

Stuttering at work I had to call the help desk at work regarding a ticket I submitted. The Technician ask me for my name, so I spelled it out. He then said you don’t have to spell it out, tell me your name, so I said I spelled out my name so I don’t stutter he was irritated and seemed not to understand that I didn’t like to say my name because I know I’m going to stutter on my own name.
