I remember in the early single runway days of the new CLK airport at Hong Kong,we had a lot of problems with dawdling pilots on arrival and departure.Arriving pilots were told to vacate say via J7 and continue on J.A large number stopped on the high speed exits,calling vacated.This was with a heavy lined up for departure,and the next arrival at 3 miles.
I would say that these campaigns are necessary,but usually don't work.
