There's a place that I fly to, which is a great place so I'm not going to mention where it is but there's one guy you occasionally get on A/G and he is barely audible, he's loud enough but he mumbles like he's drunk or on medication. He then always says that he can't hear you and you must have something wrong with your radio in quite an abrupt manner.
Funny how the radio always works when someone else is on A/G. Why do they let these people press the transmit button?
