While I wasn't by myself, it was a Dash 8 and there was probably 5 or 6 of us on board. The flight attendant said loudly "Does anyone speak french?" we all said "no" and her response was "Great! No french announcements today!" and she did the entire flight in English.
It was appreciated, but I got a feeling it was breaking the rules and she could of got in trouble. This was probably around 2001.
