Women aren't the only ones who do this. My cousin, a boy, does this all the time. My whole family does it. It's mostly people trying to be overly considerate.
I completely understand where she's coming from though, because I do this too. I'm trying to be considerate to other people so I usually let them choose because I have no problems with adapting to whatever suits their needs and I don't want to choose something they don't like.
A-"Is that what you wanna do?"
