Short of being able to replace words, saying “horder”, as previously suggested, is what I learned in therapy also. You might also try joining “your” and “order” together — no one would notice if you said “yourder” — if you can say “your” and the next word is “order”, combing both together means you’re already half way through the word “order” by the time you get to it. Also — if it helps at all — no one is listening to your opening line anyway. They’re busy looking at the menu deciding what to “yourder”. 🙂
