Majority of our flight crew are excellent but there are the odd ones who like to keep things short (saves ink from the freebie hotel pen).
Don't need to write War and Peace but a what, where , when does. Mostly it's the ones who just write the what that bug me a little. Helps enormously if we know where in the flight it happened (climb,cruise,descent etc..) and / or when it happened.
Lastly the ones who nab the choccy biccies and leave nowt but an empty wrapper on the flight decks for us engs' - very inconsiderate
