Last week.....inUSA, the home off most muppets!

JFK Controller: (to my confirmation by using the ICAO expression "affirm") "xxx was that an affirmative?"
Me: "Affirm"
Controller: "err, So is that a yes or a no?"
Me: "Well actually it's an affirm. But call it a yes if you wish."
Controller: "xxxx, are you not able to speak plain English? Give me a yes or a no, that would help us all out."
Me: "Ok, yes, affirm"
Controller: "Call Boston on xxx.xx"

"inUSA, the home off most muppets"

Kind of ironic given your complaints about effective communications.

Muppets?

The phrase "It takes one to know one" comes to mind
