Mr R Sole,
Thread creep,but the headings ending in zero I think started in LTCC,and was adopted nationally as ''Best practice''.It doesn't work so well with quadrantals which are numerous in Scotland.
Parabellum,
I certainly didn't give priority to CPA in HK,or BAW here.As far as not being ready when you say,then AFR regional take the biscuit here.You can clear them for push and start and nothing.Look through the bins and they are loading bag with a catering truck still attached.Then they turn the radio off.
At least when BAW say they are ready,then they are pushing very quickly.
