Four sector day in fine weather in a Convair - HKG to Jesselton (Kota Kinabalu) on to KL - back via BKK(?) etc. On the last sector the STC (then a junior F/O) says "Chic I have a Line Check tomorrow, any chance of PF on the last sector home?" Response: "I'm not paid to be a Training Captain". He did all four.
That does put a different complexion on things...rather a shame really...
