Depone, don't take it personally. Pedantry is trained into us through basic training, OJT, examinations, validations, supervision, standards checks, assurance vistis, SRG, ad infinitum. Just like it is trained into pilots. The difference in the controller-pilot relationship is that everyone else can hear us pick you up, whereas only your co-pilot hears you pick him up.
Standard Noise had it right - if everyone (and that is
everyone, not just pilots) transmitted only what they were supposed to transmit, there would be enough airtime for the belt-and-braces bit.
