I travel with my wife a lot and while we nearly always get upgraded to 3AC or 3DF, on occasion we're split up. Only once (out of 50+ times) has someone said no. It was 1B to 1D switch from aisle to a window. I understand his refusal but I'm sure I appeared surprised so he added, "book ahead and plan your trip better next time." We spent the entire flight pissed at each other and exchanging dirty looks. Meanwhile my wife could care less.

Moral of the story - I never ask unless it's a window-window or aisle-aisle switch. And no refusals since.
