Stallpusher, your postings are verging on schizophrenic. One moment you state:
Why do people here pontificate about things they have absolutely no idea what they are talking about?
On the inside of the four page A4 GPM forms, there is a tear off sticky strip so that it can be closed and the comments enclosed remain private. Virtually all GPMs handed back are stuck together.
and then 12 minutes later:
There is no doubt that some twit a**e licking CSD's did chuck out bad GPM forms in the past
Make up your mind! The use of the phrase 'no doubt' is an admission that this was (is) common practise.
For a long time now the forms can be sealed by the passenger.
Not that long, surely? It was only a few months ago that I saw a CSD ripping up completed GPMs, before they had the facility to seal them! And a completed GPM, from a passenger who a CSD or crewmember has had 'issues' with, can still easily find its way into a bin or shredder, sealed or not!
