That was tough to listen to. Pilot files to FAT (Fresno Air Terminal). ATC issues clearance with the full airport name. Pilot reads back "Cleared to Fresno..." and of course ATC has to correct him on his clearance limit. There isn't a VOR there with a conflicting name (unlike LAX, SFO, etc), so it was a pointless correction.
I get what he's doing regarding making sure that pilots use their callsign, but if you're only working one plane that could possibly be responding to a call, given the context, and the voice matches the one that did use that callsign less than 3 seconds before...it's a little stiff making them use their callsign again where, once again, there is no ambiguity.
Worse still, if you want them to say their callsign, then just come out and say it, "sorry, but I do need the callsigns on each call." Instead, he goes the passive aggressive route, repeating entire sets of instructions (multiple times in some cases) to prove his point, acting as though he has NO idea of who just called, and NO idea what they just said.
Calling for the radio check on SKW, that was just bizarre. Over.
