Absolutely, 1st class system that should not be messed with.
for those who have been involved in the categorisation, lets hear the funnies....
"young man in MPA who's grandmother was at death's door and who he wanted to see before the inevitable"
a few phone calls later and discovered granny had died on a number of occasions whilst young man was serving in not so popular locations!!!
and......
"married man in Gioia who's wife was having pregnancy problems which required his immediate return to sleaford"
a few phone calls later and discovered wife was sitting at home watching tv in perth and girlfriend was missing said individual in sleaford.
don't they think we might check before putting the world on hold for them......
please note that I am not knocking what is a fantastic system but just illustrating the humourous side to categorisation.
