Same thing was done for one our (bmi) Captains recently, the fire boys made a water arch at the entrance to the Bravo's (oops Cul-de-sac 1!) as he taxied in. Saw him back in the crew room and he was really chuffed about it. Also saw an Air India 747 getting the same treatment at LHR a while back on the skippers last flight. Nice to know some bloody jobsworth hasn't put a stop to it on the grounds of wasting water or something.
