Bex, Spoon etc,

I am amazed that someone got arsey about such an input. EVEN if they were both FISing, had Traffic Info and one was visual it is still good to see a decent standard of what is simply AIRMANSHIP being displayed.
Without defending the ATCO, maybe the other aircraft had called visual with the one you could see but even still, your call was not unjust.
Still, we all have off days don't we!
(BTW - were you under an APP or LARS service at the time?)
