I'm going to preface this by saying that everyday I'm at work I try to be a pilot-friendly controller. I want to help you get safely from A-to-B, provide service, etc. I'm not the guy who's annoyed that you are adding to my workload.
If you depart an airport and want either VFR flight following or pick up and IFR, please do the following. On initial call to center / approach, do not spit out your call sign at rapid speed followed by aircraft type destination crusing altitude. We are good at listening, trust me. But too often inexperienced pilots who are nervous hear a break in the comms and it's ''Center November OneThreeSixSierraNovemberRequestingFlightFollowingToOrmondBeachWe'reInACessnaSkywagonClimbingOutOfThreeThousandForSixPointFiveApproximately35MilesSouthOfSavannah".
What ATC needs to start with is your call sign, and providing the 8 other pieces of information is nice, but starting out with a "Center, November One Three Six Sierra November, request" calmly and clearly is the best way to get what you want, which is tagged up and on your way. If you're a CFI who spends time training foreign pilots, something I personally deal with, the pilots with broken English are a challenge for everyone involved - and it's even more important for them to be clear and quick so the freq isn't tied up.
