I agree that you need to say your own order, and there *should* be nothing humiliating about a stutter. It's just a different way of speaking. I'm 33 now, but when I was younger I would definitely avoid speaking and it was not the way to go. I would advise you to look that waiter right in the eye and make your order no matter how long it takes. There are people out there who love your unique form of speech, trust me. But do not avoid. It sets you back.
