Coming from a small aircraft background pilots would sometimes put 'Blah Blah system U/S' giving us no assistance whatsoever in troubleshooting.
Favourite was '70% chance of passenger pissing on seat number 6' . Our reply was '100% chance your cleaning it'
Another pet hate is a pilot not reporting the fault was fixed .If you never hear about it again you can assume it was fixed . But you cant assume so you need to chase them
