So there's no way that a resident on floor 8 can go and visit a friend
on floor 7 then?

Yes, they go down to the foyer, out the front door and type 7xx on the
key pad. Friend presses the lift release button and they come back up.

Alternatively they phone up friend, friend presses lift release button
and they can go directly to their floor.

Going back to your own floor is no problem of course.

The plus is that someone who tails you when you come into the building
can get to one floor but does not have the run of the building
