If things are busy, then keep it brief. Try not to be stupid at any time.
Controllers are people, and will treat you the way you treat them. Have you never been thanked by a controller? Has a controller never apologized for dropping the ball? I have heard controllers give compliments. If a controller gives makes a call to help you out, I think a quick "thank you" is in order. If you hinder them by giving them BS when they are busy, it will urk them.
HERE IS MY BIG PROBLEM
What about people who talk so soft and quiet on the radio that ATC asks them to SAY AGAIN after every transmission????????????????
That drives me bonkers
**If you hear me say "with you", please overlook me as I have fallen off the wagon. I have a "with you" calls anon. meeting next week.
