For #1, I think I'd go more with, she (and two other people) didn't know how to process the option I'd chosen, though they eventually figured it out after X minutes. Again, pointing out that there was a way to process your option, but none of the three knew it. More training!
Also, I would roll #3 and 4 together. I know what you mean about "talked over my head" and "talked about me," but I don't think those are objectively bad things. It was really how she spoke and what she said that were rude, and that plays into #4 only. For example, I've had people in a store say, "Barb, this customer has a question. Do you know where she can find the TPS forms?" Really, that's talking about me while I'm right there, but it's done in a perfectly polite and professional way.
I think the quote you gave would make a great example for #2. It gives exact words, and it's hard to picture them in anything but a snotty tone.
What was said over my head was something like this:
Clara: Rob, can you come here and help us with a form?
Rob: Sure, what's up?
---Rob walks up behind me, and is now standing behind, and to the side of my chair. Clara & my intake person are sitting on the other side of the desk, facing me---
Clara: <Explains I don't want to check either box & how they can't figure out how to enter that>
Rob: Why would she not want to check either box? You have to check a box
Clara: Well, some people have problems with these boxes I guess. Some people have a lot of problems these days.
Me: The form clearly states that I don't have to check any of the boxes, and states what it means if I don't check either box
Clara: No, you're reading it wrong <explains it to me incorrectly>
Me: No, reread this part and this part, they contradict what you just said
Rob: <reading the boxes over my head> Is this really a problem? It's just a simple form.
Clara: (to Rob) I know. Most people just check option 1 and move on. This isn't a big deal. (to me) You should just really check option 1 because <explains form incorrectly again>
Me: I do not want to check option 1. I have already told you that I do not want to check option one. I am not checking an option because <rereads what the form says>. I don't know what to tell you about your computer issue, but as the form says I can choose not to check either option, that is what I'm doing.
---Rob must have walked away, because I glance back, and at he's not longer behind me---
Clara: Look, everybody just checks option 1. I don't know what to do with the computer. It's really easy, just check option 1. It means <explains it incorrectly again>
It was my original intake person, who continued to stare at the computer screen, who eventually said "oh! look, if I scroll down, there is a place I can make a note that the patient didn't want to check either box". And then Clara looked at that, didn't say anything, and sort of stalked away.
Given the Clara's badge said that SHE is a full-time employee, I wonder how many people she badgered into picking one of the boxes, since she didn't know that there was a place to click if you didn't want to pick either option.
