Quite agree. A very dangerous practice is the aircraft having to call Ramp on box two to find their gate, while they have just vacated the runway and are reconfiguring and taxiing around a very large and complicated airport - instead of ATC Ground simply looking it up.
So one pilot has to taxi and deal with the rapid fire radio calls - and doesn't have a spare hand to write anything down - while the other pilot is away on box two trying to find out the gate number. Absolute madness, and frankly very dangerous at a big busy airport.
Ground control must, or should, have access to a screen displaying the gate numbers, and they really should stop asking the aircraft to get this information.
Also what is Ramp all about?? I know it is owned by a different authority, but Ground should deal with that.
