Always found the 'one man push' procedure at Schiphol bizarre, single tug driver to do chocks, pins, pushback, etc etc...
Compared to the UK for example, where as a minimum you'll have a headset man, pushback driver, and a wing walker.
But hey ho, what do I know
Was at OSL not long ago and witnessed a single person tow the aircraft onto stand, chock it, put the bridge on, nip into the cockpit to do whatever brake riders do, come back down, and drive away in the tug. Impressive!
