Surely in these modern times an alternative to grey concrete blocks can be found? It is a bit like flying out of the Eastern Bloc at times.
I'm not knocking the airport on this one, but it's time to decide if the arrangements are permanent or not.
If the drop-off road is never going to see action again then can it be made secure AND pleasant on the eye? How about some gardens or greenery? (not like the few half-dead trees lining the drop-off car park!).
Again, it all contributes to a passenger's experience.
