In the run-up bay overheard a pilot advise tower there was some sort of debris on the runway. Thought it might be a dipstick. Car 5 goes out to investigate.
Tower : Car 5, can you spot that debris near the threshold? Might be a dipstick.
Car 5 : It's not a dipstick, although one might have been involved. It's a fuel dipper.
Tower : Roger.
Car 5 : I won't say who it belongs to on air, don't want to embarrass them.
Tower : Roger.
Car 5 : Yeah, it belongs to Alpha-Bravo-Charlie, but as I said, I don't want to embarrass them.
Tower : Good idea.
