What Gets You Mad When You are Ordering Food/

It annoys me when the servers interrupt me in the middle of giving my order because it was not given in the specific order that they need to hear it. Probably because they have to input it in their computer in a certain way. Then they forget what I've already told them because they were so insistent on interrupting me in the first place. Why don't they train customer service staff to NOT interrupt customers? That is the height of rudeness in my opinion.

I usually don't get mad at servers in restaurants. But it has been annoying in the past when they don't get my order right. Like when I ask for well done it comes back too well done. And when I asked for something else instead of what the main dish comes with and they said they forgot. But I guess, they can't be perfect anyway, so I just never worry about these things too much.
