Whilst on descent into Subic Bay NAS (USN Naval Air Station), in the Phillipines a few years ago in a military P3, the female ATC issued us our arrival clearance at machine-gun speed, so fast, in fact, that no-one onboard understood even a part of it!
Our Captain, having been around the world a few times, said in a slow Queenslander type voice,
"Now we've heard how fast you can say it, lets see how s-l-o-w you can say it", and had no further troubles with her.
Cheers
