Take the A/G radio guy in the tower, who, when asked for some circuit traffic information (due to poor vis in rain) replied "There's two". !! I don't give a how many there are, where are they!! One apparently was doing a fanstop, but turned out to be turning downwind about 5 miles away from the airfield.
There's no requirement for an Air/Ground operator to even be able to see the cct traffic - could be a receptionist with a handheld etc. I've been in to one place where the guy cooking breakfasts was doing the radio with and icom - it can be so variable from place to place
