Tried to drop off a passenger at Terminal 1 destinations, but my car was too high (2.2m) to enter the carpark drop off point (max 2.1m). I asked 2 separate members of staff where i could go to do my drop off. Both shrugged their shoulders and told me to move along. Seemingly, it was not their problem. I had to drop off my passenger in the middle of the road near the terminal. I still don't know where i should go next time. Very poor and unhelpful site staff.
