ATCO, had a run in with one of your mates last night about this callsign business. You are correct.......how about a bit of professionalism and pride from that side of the mic as well.
My comms is better than average and yup. heaven forbid I should slip up and forget to mention my callsign in the heat of the moment.....but ffs, it was like I had pissed in his flower garden.
