They spend; and, along with MOL, I am enormously glad they do. It gets them hours, keeps them away from Biz Jets, and subs LOCO fares to sunny destinations for the rest of us.
I would do exactly the same thing if I was armed with a Blue Book and constantly having to swerve the 'sniggering' employment questions of the 'friends of the family'!
I agree that WWW is quite correct in his assertion that BRK really should guarantee a minimum number of hours in their FR contract. Surely this shouldn't be so hard to do given the rising demand for FR's product. Without this 'safe-guard' an infinite number of 'opportunities' could be said to exist and the hours would ultimately drop as more eager dowry's are paid. It would be rather akin to a pyramid sale, each 'dowry' subs those above, until the whole scheme tumbles.
As already numerously stated. I am am a huge fan of FR and BRK. I hope that all Wannabes get their chance to join, and share in the kudos.
