How rude was this on a scale of 1-10?

I was ordering at a restaurant and being a bit picky about things and I asked them to cut a wrap for me in half and the girl literally said there's a knife behind you, you can use that, (butter knifes). I'm surprised I didn't roll my eyes at her.

I was like you don't cut it skeptically, she said no. I was tempted to push this further, decided I didn't have the energy to argue and was like whatever.

For the record, no way in hell a butter knife can cut a wrap.
