Ops departments W@nkers one and all.
Last week we had one Capt given a slot by his ops people which was 20 mins earlier than the slot we got from FMP (incidentally, I find that the guys at flow are amenable to a bit of slot jiggling, as long as you don't rip the arse out of it).
He didn't go until the slot time we had for him came up. As far as I'm concerned, the AFTN terminal in the VCR is the one I take slots from, not some whispered phone call from some halfwit 300 miles away who doesn't know an airbus from a number 31 bus!
