I suspect that is why the F/A was a little more insistent on the CDG flight than you might find them on the flight to Omaha.
I thought so too. I used the downstairs F lavatory on the 747 by mistake, not realizing it was no longer part of the C cabin and got corrected by the FA with an imperative tone.
Generally, I try to stick to the rules of well behaviour which ask to adhere to your cabin. But then then it's temping in a single aisle aircraft and people with children or the ones in the very front rows often succumd to it. Somewhat understandably ..
