Gotta agree on the Emerald guy; in the middle of a long day of travelling around central Qld I had a passenger drop his wallet on the tarmac, the refueller found it (with the LARGE wad of cash inside), rang the passengers office, called his end-of-day destination, and had the wallet (complete with ALL contents) couriered on to the destination and returned to the owner, before he even knew it was missing!
There is now also a Shell Avgas truck on-call at TWB who is very good; and the fellows at Bundy are always up for a yarn and a gander at the latest pix in their aeroplane photo collection.
Regards.
