One day, while flying over the Rockies with a strong jet stream and many turbulence reports in the Denver airspace, I heard Denver Center ask for ride reports.
"Good day, Denver. United 123 with you at FL 350."
"Roger, United 123. How's your ride?"
"Well, the captain is having his lunch, and he just jabbed himself with his fork; so we could call it as moderate turbulence."
"Thanks, United 123. Break, break. Air Canada 456, how's your ride at FL350?"
Air Canada 456:
"Sorry, Denver, we can't tell. We haven't eaten yet."
