Mr B,
Perhaps the bloke that eventually does the flight has been called off reserve! They might have called you first hoping to not have to pay the reserve guy heavy overtime.
It might be a little shortsighted to start a blackbook of names without having the full picture. Poor bugger might just be doing what he has to do ie. go to work when called off reserve.
I'm sure that there are plenty of "helpers" out there but that might not always be the case.
