Or maybe it's because the standard of handling from Swissport has nosedived spectacularly in the last few years, and they are now as bad, if not worse, than the Circus. The passenger handling op from Swissport is particularly poor, and dispatchers seem to have no understanding thet they need to have some contact with the flight deck during the turnaround and not just disappear for 30 minutes at a time.
Guess I know which handlers wear the big clown shoes and red noses these days.
