I've personally witnessed someone getting a b****ing over the radio within minutes of starting up at Popham. The guy had taxied from one end of the flight line to the other and made the heinous omission of not announcing his intentions to the guy behind the desk.
I was absolutely shocked. I completely agree that A/G radio is not the appropriate medium to issue b*****ings, regardless of the perceived faults of the person on the receiving end.
Come on Popham! You used to be great, and now you're driving customers away. If you're unsure how your radio operators ought to behave, go to a club like White Waltham, and ask them to show you. They are polite and know when to let something slide and when to have a DISCREET word. Its that level of CUSTOMER SERVICE that keeps people coming back.
