This is a good example of needing to know that not everything that's done in the tower will come over on the frequency. If this were me, being busy with the go-arounds, I'd more than likely have a coordinator position (or even supe) doing the coordinations with approach control for all the misses. When AMX asks for higher (and at 1st he didn't even bother to specify an altitude, so what's the controller supposed to clear him to? heaven?), and I've heard the guy give numerous go-arounds 130 and 2, I figure that's standard. Higher requires coordination, which is likely being done by someone else at another position. (e.g. "Approach, AMX requesting climb to 6 for windshear" "Approved" and then coordinator tells local) That's typical procedure. But the "helpful harry" anonymous pilot who further congests a busy frequency with his interjection probably doesn't know that, and the controller's "Rah-jer" in reply was perfect. I don't blame the pilot for not knowing, but that's why he should just do his job, and let the controller do his, which often includes off-air coordinations, which when done quickly and without interruption, will often get the pilot exactly what he needs. e.g, give AMX 3, do the coordination for 6, and then re-clear him to 6 before he leaves 25.
