The French demo these days should be played once doors are closed. But old habits die hard and with there being no actions then people can usually still listen in. Strictly speaking, a foreign demo/tape is not obligatory but we always strive to do one and so doing it then on occasions can help when there's a short taxi out. It's much better than some airlines who play the foreign after take off. I.e American.
Broad accents. Nothing can be done about that and is an age old problem. I had difficulty understanding announcements on a QR flight yesterday and they too occasionally have to do manual demo. I also find some carriers play the video way too quietly.
With EZY you may be interested to Know that the English demo is only being read whilst the automated PA's are being updated so the reassuring queens English accent of Phil Gayle (of big breakfast news fame) will be back with you shortly.
