I will concede my own part in using extra words in speaking to ATC, even in foreign locations. We are a product of our training and our culture. I leaned to speak “pilot speak” like most, from my instructors of the day, who would have themselves learned from others like them. ATC hasn’t always been the best guide/teacher of correct ICAO speak. We need to do better and it is discussions like this that will help improve it.

At least you don’t hear, “10-4” on the radio. That is long gone (good buddy 😉 )
