Lovely older BA skipper I flew with many years ago had it right. He had a line check with a checker who was renowned for two hour debriefs. As they were walking back into the crew building he turned to the check and said, "I usually get a 4 for appearance and a three for everything else. Goodnight."
And walked off to the car park.
I managed to do something similar many years later, so at least I learned something from the line check
