Or just try saying your name, and if you get too stuck, spell it out or write it down. Just laugh it off and say, “I stutter, having a tough time with my name haha..” or just “Having a hard time talking today” if that’s easier. At least that’s what I do. I have a severe stutter that can get very bad sometimes. I had to spell out my name last time I went to Petsmart because I literally couldn’t get it out. The cashier was super nice though, and I just shrugged it off. It’s not the end of the world! You’ll be fine :)
