My stutter code name used to be Sean. It was nice and easy for me to say at places. It started to get weird when I'd be with someone I knew or the other person behind the counter has heard me say my real name before. I just started saying my real name regardless if I stutter or not. If I stutter and they laugh or something I tell them I have a speech problem and not to make fun of me. Usually they'll comp your order or throw in something for being rude.
