(it) doesn't bother me at all

I have no objection to this. Sure, you can open the window in here—it doesn't bother me at all. A: "I think we're a little lost. Do you mind if we stop and ask the people in that gas station if they can help us?" B: "Sure, doesn't bother me at all." You'd rather go to the 8:30 movie? Yeah, OK, doesn't bother me at all.
