Kind of like a 'supe' in a luxury apartment tower. Obviously at the beck and call first of the pilot, down to a passenger who just threw up in the toilet. In this case do the tanks ever have to be managed manually?

Typically you'd empty from inboard and out, but with quads it becomes a bit more complex. I think the 380 has four tanks per wing plus the trim tank.
Looking at this diagram, my guess is something like this:
- Inboard engines fed from feed tanks "2". Outer engines fed from feed tanks "1".
- Inner tanks transfer to feed tanks.
- Mid tanks transfer to feed tanks.
- Trim tank transfers to the feed tanks once at a certain fuel level or at a certain time before arrival.
- Outer tanks transfer to the feed tanks.

That's pretty much it according to page 158 of the following PDF
