Yes, it does make a good deal of sense; there is, if not a world, a good deal of difference in the meanings of those two lines and also in what the word choice suggests about the power relationships between the speaker and the person to whom the offer is directed. And, yeah, I've spent far too long tweaking sentences because they didn't have the right beat or sound; that tends to be how I figure out a character's voice, based on the sound and cadence.
