'heard that the inbound crew that morning had a big "cook up" before arrival in SYD.
Croisants etc and left them wrapped up in paper towels in ovens !
New crew came on -didn't check ovens. Turned them on to 250^ to heat ovens before loading meals.
BINGO !!!!
Wonder how much that exercise in slackness cost them.
We would never to that on QF.........
