I have to say, the majority of RT 'hates' posted on here don't bother me in the slightest, however, after giving tfc info, 'Got him on TCAS' does irritate as there is nothing ATC can do with that info. If you are not visual, it doesn't count. I am sure there is plenty that we do that irritate pilots too. A lot of it is down to not understanding why it HAS to be said and that applies to both sides.
