Dns,
You're the one being aggressive and arrogant. You've made statements that show you simply don't understand what is standard RT phraseology in the US and you've assumed that just because it's done a certain way in your neck of the woods, it should be the same elsewhere.
Just to make this simple for you......
In Domestic Ops in the US, one can "Declare an emergency" as opposed to saying "Mayday, mayday, mayday". Done it myself twice and it worked well without any confusion displayed by ATC.
Also, "Roll the trucks" while not specifically mentioned in the FAA Pilot/Controller Glossary, is a colloquialism used by US Pilots, within the US. It's such a common phrase that I would be amazed if any ATCO would be unaware of its meaning.
Perhaps you should go back to the CC forum and pontificate about matters you are actually well versed in, rather than spouting off about something you obviously aren't.
