I shall remember that the next time I look at my adjacent, non-LARS unit military airfield on radar, with nothing wearing one of their squwks, and the staff of Tower / Ground / Approach / Director / Zone / Talkdown.
That'll be when I've got 4 IFR trainers, 3 IFR inbounds, a few on LARS and all on the same frequency. That'll be handled by one in radar, one in tower, one on a break ready to relieve one of the other two when necessary
Still - at least I don't have to try and co-ordinate with the person (not) sat next to me - makes life a bit easier I suppose
