The one who writes in “Nil” as the first entry then writes “For Info” as the second entry.
"I only wrote 3 items as the page is full", what’s wrong with PTO.
The one, who writes nothing in the book, then tells you that the APU shut down on all sectors during engine start.
The one who tells you it's a fine aircraft, nothing wrong and the Cabin log has pages and pages of items to attend to.
The one who demands you to be there when they arrive, so they can sneak off and leave you monitoring the APU and the cleaners.
The one, who calls for an engineer, doesn’t specify what the problem is, you go to the aircraft, and then you have to return to the office for the follow up action from the AMM/TSM etc.
The one, who calls for an engineer, then doesn’t specify what the problem is so the wrong guy turns up and have to call for the other trades.
Pre departure, the captain, panic call need an engineer, passengers are sat waiting to go, arrive to be told, “she's got a problem”, speak to the purser, “I've put something in the cabin log” and a delay follows.
I don't care, it's not a problem, that's what we are here for, and it all goes on the bill, and its job security.
