Love the Bill Bryson comment that staff at US airports are always so mean and grumpy because having to attend to passengers gets in the way of their stuffing their faces eating time...
Earlier this year my wife and I flew from Cagliari, Sardinia, to Rome Fiumicino. Waited and waited and waited - finally the bags start rolling down the carousel (the wrong carousel, according to the arrival monitor, but what the hell).
After a while the carousel stopped and the monitor announced that our flight's baggage drop was complete - with at least a third of us still standing there (like boludos, but that's not very Italian).
As we all race to customer service a uniformed guy comes from behind an Official Door, waving his hands and talking fast. Turns out the baggage guys hit their break time just about the halfway mark of unloading our plane, but not to worry: they'll be back to work in twenty minutes and you'll all get your bags. They did, and we did.
All airports are equally terrible when you're tired, frustrated, delayed till you miss your connection, etc., etc., etc.
