I ordered at Chipotle today (NOT ONLINE)

I ordered at Chipotle today (NOT ONLINE) Normally, I order Chipotle online to avoid any stuttering that may or may not happen. Today, I walked in to the store and saw a lot of people in line... I left to look for other places to eat but eventually went back in. By that time, there was no one around and only the restaurant staff members. I walked right up and tried to place my order but I couldn't get past "Chicken S-S-S-S-S-S-S-S-S-S-S alad" ..... Yeah it was that bad. I am really bad with S's and today was no exception. I continued the order with adding other ingredients with no problem (brown rice, pinto beans, corn, lettuce (almost stuttered but managed not to) . I don't know what it is but its hard for me to speak to someone when facing them in person. I think I do better on the phone at times... I don't know but I hate this feeling. I'm also quiet at work, of course, and only speak when needed. But I've been having anxiety issues because of weekly meetings and I may need to go over some things during these meetings... it's really starting to affect me and making me think whether or not I should look for a new job :(
