whadaya mean, whadaya mean?

Today I can report that I react so strongly to the lady who has lived in her car for 25 years that I can't be in the same building with her. I suppose I developed the sensitivity last time I had to interact with her, but this problem leads to exchanges like this:
Lady: Would it be possible to vacuum the footspace of my car?
Me: Yes, you can vacuum it.

Wanna know what was actually said? Here you go:
Lady: Please vacuum my car.
Me: I don't think so.
