I feel you! I avoided drive thrus or had my brother or friends do it for me for so long. However I got a job and hardly ever packed a lunch and my hangry overcame my anxiety so I forced myself to navigate it the best way I could. Speaking slowly helps, if you got order number pull it up and show it to the person, if you don’t got that luxury then still pull it up and read it slowly. I find I stutter less if I read rather than freeballin it lol. If they got numbers on the menu that are easier to say than the actual item then go for that. I do challenge you to say the things that are hard though rather than taking the easy way as repetition regardless if you’re successful will give you confidence to do it again and have an opportunity to be successful. Anyway good luck and I hope you have a minimal stress free day!! 🍀
