You only have to be nice to the staff at the CAA to get treated well, FCL is run (generally) by a bunch of very nice people, who deal with up to 100 pilots a day each, pis*ing and moaning about things that you don't like, will not get you far.
The CAA are there to help you and everyone affected by aviation safety, even if it seems that sometimes they just want to stop you getting in the air.
If you are unhappy with the services that PLD provide then complain in writing (with clear reasons), I promise you that it is worthwhile.
PS
AOPA were one of the main driving forces behind the PPL being covered under JAR regulations. also the BMA wanted the SLMG's to remain a national.rating
