Where's the humour in that?
Ovens are only employed on serious, long day out operational ac, as are engineers, whose only familiararity with the oven, is the Galley Master, which they switch off during MAD serials or compass checks
Flt Deck and Navs are shown around the galley as part of the OCU course, so they are familiar with the ac layout
In fairness, Flt Deck and Navs willingly help out in the Galley in long transits, but under close supervision from the AE cadre - I mean - you wouldn't let your 2 year old supervise the Barbie - would you?
