To ATC ..Gold Coast Ground freq
To the person on GOLD COAST ground freq the other day.
Your comment to my student 'Not good enough'

AIP comms does not have that gutteral term written anywhere.
By the tone of your voice you were having a bad day.
If you cant hack the job mate get out of the kitchen.
Your superiors have been informed but I guess that wont go anywhere.
