Working from an international airport, I also often wait for taxi clearance but have never logged ground running time before the aircraft's first movement.
We do exactly the same.
I didn't actually notice any sign of a sense of humour...
I did say it was poor.
If I'm in a position to recruit another co-pilot (recruited two in the last year or so), possibly to help them "do a Flingingwings", I'll be perusing applicant's logbooks very carefully and asking deep and meaningful questions at hours logged by ex-offshore co-pilots, especially ones from Humberside with a share in a light aircraft.
Well if they have a share in a light aircraft, just think of all the PIC time they'll have logged, and not had to put up with the inane banter of some old know-it-all crusty Captain across the cockpit!
You got to love a sense of humour!
Cheers P, at least I had a laugh tonight.
