Hey, another PWS who struggles with 'S' here! I can't even say 's' correctly when I'm not stuttering, it always comes out as 'ts'. Back to the main point, I know how ordering food can quickly turn into a nightmare. But tbh, ordering food is one of the few areas where I feel like I've been making real progress recently, so I hope you'll be able to manage the same. Try not to give think too much about what people think, yes I know it's cliche af and also really hard as your brain will always want to do otherwise, but hang in there. Speaking to people in person though, that's still something that I (regrettably) tend to avoid lol
