Moorabbin last weekend.
Unidentified aircraft approaching from somewhere. Runway in use was 35L.
Radio call was "17 left."
That was it... just simply... "17 left"
Tower responds with, "I think an aircraft just gave an inbound call for 17 left, please identify yourself."
Calls back with "35 right."
After multiple calls from the controller, he replies back with simply "Warrior ABC at Brighton, request 35 right."
This guy wasn't an international student. It was very strange and I haven't heard anything like it before. He just either couldn't be bothered, was having a massive brain fade or he was suffering from an unknown condition.
The week earlier heard a woman effectively arguing with the controller about him not giving her traffic after he clearly told her about traffic when she gave her inbound call. Reviewing the GoPro audio track later, she over transmitted when he was giving it to her and she was none the wiser until he queried her proximity to said traffic shortly after. It pays to be patient with pressing the transmit button sometimes when giving your read-back.
